  • The STEVAL-ILL043V1 demonstration board is a high-PF flyback configuration in order to drive a new design of the 75 W LED array based on the L6562A controller, with a much reduced BOM cost.

    This configuration uses an isolated feedback with an optocoupler and a secondary side reference/error amplifier. The inverse buck converter based on the L6562A is used for constant voltage and constant current control in double dimmable channels.
    The L6562A is a PFC controller operating in Transition mode. The highly linear multiplier includes a special circuit, able to reduce AC input current distortion, that allows wide-range-mains operation with an extremely low THD, even over a large load range.
    The inverse buck converter shows good performance in terms of power switch control and conditioning circuitry signal for the current sensing. In fact, this topology of converter allows easy driving of the switch referred to ground by using an L6562A driver.
    An integrated auxiliary power supply provides an energy saving action and a remote control monitoring function for the system.
    This ballast designed by using the L6562A and the buck inverse converter offers more advantages in terms of output current and voltage stability.
    The key benefit is the very high efficiency that, at full load, is almost 90%.

    Key Features

    • Mains voltage range VACmin= 165Vac, VACmax= 277 Vac
    • Minimum mains frequency fl = 47 Hz
    • DC output voltage Vout= 65 V
    • Maximum output current Iout= 1.5 A
    • Maximum 2fL output ripple ΔVO% = 1.0%
    • Minimum switching frequency fswmin= 40 KHz
    • Expected efficiency: 90%
    • RoHS compliant
