  • EVL185W-LEDTV
    185 W power supply with PFC and standby supply for LED TV using the L6564, L6599A, and VIPER27L

    The EVL185W-LEDTV is a high-end demonstration board tailored to the specifications of a typical LED TV application. The peculiarities of this design are the very high average efficiency of about 90%, without synchronous rectification, and very low no load consumption of 100 mW at 230 Vac. The result is that this converter is compliant to the most demanding ENERGY STAR® eligibility criteria. The architecture is made up of two sections, based on a three-stage approach: a 10 W standby supply using the new VIPer27L, which delivers the 5 V standby dedicated to supplying the microprocessor and the logic circuitry, and a bigger section composed of a front-end PFC, using the new TM L6564 and an LLC resonant converter, using the L6599A, delivering three output voltages: 12 V dedicated to supplying the TV panel, 24 V to supplying the audio power amplifiers, and 130 V dedicated to the backlight.

    The PFC stage delivers 400 V constant voltage and acts as the pre-regulator for both the LLC stage and the standby supply.

    An external signal, referred to secondary ground, turns the PFC and the LLC stage on and off.

  • EVL6564H-100W
    100 W transition-mode PFC pre-regulator demonstration board based on the L6564H

    This demonstration board is based on the new transition-mode PFC controller L6564H and implements a 100 W, wide-range mains input, PFC pre-conditioner suitable for ballast, adapters, flat screen displays, and all SMPS having to meet IEC61000-3-2 or JEITA-MITI regulations.

    The L6564H is a current-mode PFC controller operating in transition mode (TM) which embeds the same features existing in the L6564 with the addition of a high voltage startup source. These functions make the IC especially suitable for applications that must be compliant with energy saving regulations and where the PFC pre-regulator works as the master stage.

    The EVAL6564H-100W implements a power factor correction (PFC) pre-regulator 100 W, continuous power, on a regulated 400 V rail from a wide-range mains voltage and providing for the reduction of the mains harmonics, allowing the European EN61000-3-2 or the Japanese JEITA-MITI standard to be met. The regulated output voltage is typically the input for the cascaded isolated DC-DC converter that provides the output rails required by the load.

  • EVL6699-90WADP
    19V - 90W Adapter with PFC for Laptop computers using the L6563H and L6699

    The architecture of the EVL6699-90WADP is based on a two-stage approach; a front-end PFC pre-regulator based on the L6563H TM PFC controller and a downstream LLC resonant half bridge converter using the new L6699 resonant controller. Thanks to the chipset used, the main features of this design are very high efficiency, compliant with ENERGY STAR eligibility criteria (EPA rev. 2.0 EPS) and very good efficiency at light load too, compliant with the new ErP Lot 6 Tier 2 requirements. No-load input power consumption is also very low, well within the international regulation limits.

    The controller of the LLC stage is the L6699, integrating innovative functions such as self-adjusting adaptive deadtime, anti-capacitive mode protection and proprietary “safe-start” procedure preventing hard switching at startup.

    The PFC stage works as pre-regulator and powers the resonant stage with a constant voltage of 400 V. The downstream converter operates only if the PFC is working and regulating its output voltage. In this way, the resonant stage can be optimized for a narrow input voltage range improving the efficiency of the primary side power components.

    The transformer uses the integrated magnetic approach, incorporating the resonant series inductance. Therefore, no external, additional coil is needed for the resonance. The transformer configuration chosen for the secondary winding is centre tap.

  • EVLALTAIR05T-5W
    ALTAIR05T-800 5 W wide range CV-CC optoless adapter demonstration board

    This board implements a 5 W (5 V / 1 A) wide range mains battery charger with constant voltage-constant current, tailored for AC-DC chargers for mobile phones and adapters and other hand-held equipment.

    The core of the application is the ALTAIR05T-800, the first “All-primary sensing switching regulator” of the new ALTAIR family.

    The IC combines a high-performance low-voltage PWM controller chip and an 800 V, avalanche-rugged Power MOSFET in the same package.

    The PWM chip is a quasi-resonant (QR) current-mode controller IC specifically designed for QR ZVS (zero voltage switching at switch turn-on) flyback converters.

    The device is capable of providing constant output voltage (CV) and constant output current (CC) regulation using primary-sensing feedback. This eliminates the need for the optocoupler, the secondary voltage reference, as well as the current sensor, while still maintaining quite accurate regulation.

    In addition, it is possible to compensate the voltage drop on the output cable, so as to improve CV regulation on the externally accessible terminals.

    Extremely low consumption under no load conditions is ensured thanks to a controlled burst-mode operation that, along with the built-in high-voltage startup circuit and the low operating current of the device, helps minimize the residual input consumption. Although an auxiliary winding is required in the transformer to correctly perform CV/CC regulation, the chip is able to power itself directly from the rectified mains. This is useful especially during CC regulation, where the flyback voltage is generated by the winding drops.

  • EVLALTAIR900-M1
    Double output SMPS for power line application using ALTAIR04-900 primary controller

    This board implements a 7.5 W double output wide range mains adapter with constant voltage - constant current, developed to build an innovative AC-DC adapter to supply a complete power line communication based on the ST7580.

    The power supply provides a 13 V output voltage to supply the power line modem (PLM) and the analog circuitry, and a post-regulated 3.3 V to supply digital circuitry and an optional external microcontroller.

    The board uses the new ALTAIR04-900, a quasi-resonant (QR) current-mode controller IC specifically designed for QR ZVS (zero voltage switching at switch turn-on) flyback converters, which combines a high-performance low-voltage PWM controller chip and a typical 16 RDS(on), 900 V, avalanche-rugged Power MOSFET in the same package.

    The device is capable of providing constant output voltage regulation using primary-sensing constant voltage loop (CV loop). This eliminates the need for the optocoupler and the secondary voltage reference while still maintaining quite accurate regulation.

    In addition, by using the primary constant current loop (CC loop), it is possible to set the maximum deliverable output current without any secondary components or current sensor.

    The board implements several protections that considerably increase end-product safety and reliability: auxiliary winding disconnection (or brownout) detection, shorted secondary rectifier detection, and transformer saturation protection: all of which are in auto-restart mode.

  • STEVAL-ISA078V1
    High efficiency synchronous step-up regulator based on the L6926

    The STEVAL-ISA078V1 demonstration board is a high efficiency monolithic synchronous step-down regulator capable of delivering up to 800 mA of continuous output current and of regulating the output voltage from 0.6 V up to VINthanks to the 100% duty cycle operation capability.

    The control loop architecture is based on a constant frequency peak current mode, while high efficiency at light loads is achieved by a low consumption functionality.

    The very low quiescent current (25 μA) and shutdown current (0.2 μA) means that the device is very suitable for supplying battery-powered equipment like PDAs, hand-held terminals, DSCs (digital still cameras) and cellular phones.

    The switching frequency is internally set at 600 kHz, but the device can be externally synchronized up to 1.4 MHz. An internal reference voltage of 0.6 V (typ.) allows the device to regulate a minimum output voltage of the same low value.

    The low MOSFET RDS(on)ensures high efficiency at high output current.

    Additional beneficial features are: hysteretic UVLO, OVP, constant current short-circuit protection, Power Good and thermal shutdown.

  • STEVAL-ISA126V1
    5 V-2 A, 115 kHz flyback with temporary extra-power management based on the VIPER28HN

    The STEVAL-ISA126V1 is a 5 V-2 A application with 3.3 A peak current capability for 1.9 sec, using VIPer28H, a new off-line high voltage converter from STMicroelectronics.

    In some applications an SMPS, normally supposed to deliver a certain amount of power, from time to time undergoes load peaks that can be even two or more times as much, but only for a time interval which is short if compared to the thermal time constants of the power components. Typical examples of such loads are printers and audio systems.

    In these cases, it is more cost-effective to thermally design the system for the maximum continuous power and not for the peak power demand, which will be sustained only for a limited time window.

    Such a design is possible thanks to the EPT function of VIPER28H, which allows the designer to fix the maximum time window during which the converter is able to manage the peak power still maintaining output voltage regulation. If the overload lasts more than this time window, the converter is automatically shut down in auto-restart mode, in order to avoid the damaging of the power components.

    The STEVAL-ISV003V1 is a demonstration board which implements the microinverter concept and is designed to optimize the power production of each single solar panel by means of DC-AC conversion. The conversion system is capable of both grid synchronization and maximum power point tracking (MPPT) thanks to the use of an advanced control algorithm implemented in the 32-bit STM32 microcontroller. The MPPT function is based on the perturb and observe (P & O) concept which seeks the best operating point of the panel, thus maximizing the energy produced under any environmental condition. The grid synchronization algorithm has the advantage over standard solutions of a decoupled control of active and reactive power. The STEVAL-ISV003V1 demonstration board uses a high-frequency (HF) isolated DC-DC converter with interleaved current and an optimized full-bridge DC-AC inverter. The typical solar panel voltage is first stepped up to about 400 V and then converted into AC to create a sinusoidal output.

    An LED display provides a user-friendly interface for the end user which allows the monitoring and/or modifying of some of the main operating parameters. Two modes of operation are available and can be selected to allow either open-loop operation or closed-loop operation in synchronization with the grid.

    In open-loop mode the sinusoidal reference is created internally by means of a standard lookup table, while in closed-loop mode, a sinusoidal voltage feedback which is proportional to the grid voltage is used. This system can be connected to a 50 Hz network (STEVAL-ISV003V1) and to a 60 Hz network (STEVAL-ISV003V2), based on local requirements. The RS-232 interface can be used for serial data transfer of specified voltage, current and current signals.

    Furthermore, the STEVAL-ISV014V1 can be used to supply a type-B USB compatible load by an external Li-Ion battery. In this case, the L6920 voltage boost controller will regulate the battery voltage up to the 5 V required by the USB standard.

    Finally, the STEVAL-ISV014V1 has a dedicated charging monitor circuitry implemented by 4 LEDs and by the TS339 quad comparator.
