LNBP20 / LNBP1X series
LNBP supply and control voltage regulator (parallel interface)
Feature summary
Complete interface for two LNBs remote supply and control LNB selection and stand-by function Built-in tone oscillator factory trimmed at 22KHz Fast oscillator start-up facilitates DiSEqC encoding Two supply inputs for lowest dissipation Bypass function for slave operation LNB short circuit protection and diagnostic Auxiliary modulation input extends flexibility Cable length compensation Internal over temperature protection Backward current protection via the coaxial cable. Since most satellite receivers have two antenna ports, the output voltage of the regulator is available at one of two logic-selectable output pins (LNBA, LNBB). When the IC is powered and put in Stand-by (EN pin LOW), both regulator outputs are disabled to allow the antenna downconverters to be supplied/controlled by others satellite receivers sharing the same coaxial lines. In this occurrence the device will limit at 3 mA (max) the backward current that could flow from LNBA and LNBB output pins to GND. (See continuous description).

Description (continued)
For slave operation in single dish, dual receiver systems, the bypass function is implemented by an electronic switch between the Master Input pin (MI) and the LNBA pin, thus leaving all LNB powering and control functions to the Master Receiver. This electronic switch is closed when the device is powered and EN pin is LOW. The regulator outputs can be logic controlled to be 13 or 18 V (typ.) by mean of the VSEL pin for remote controlling of LNBs. Additionally, it is possible to increment by 1V (typ.) the selected voltage value to compensate the excess voltage drop along the coaxial cable (LLC pin HIGH). In order to reduce the power dissipation of the device when the lowest output voltage is selected, the regulator has two Supply Input pins VCC1 and VCC2. They must be powered respectively at 16V (min) and 23V (min), and an internal switch automatically will select the suitable supply pin according to the selected output voltage. If adequate heatsink is provided and higher power losses are acceptable, both supply pins can be powered by the same 23V source without affecting any other circuit performance. The ENT (Tone Enable) pin activates the internal oscillator so that the DC output is modulated by a 0.3 V, 22KHz (typ.) square wave. This internal oscillator is factory trimmed within a tolerance of 2KHz, thus no further adjustments neither external components are required. A burst coding of the 22KHz tone can be accomplished thanks to the fast response of the ENT input and the prompt oscillator start-up. This helps designers who want to implement the DiSEqCTM protocols (a). In order to improve design flexibility and to allow implementation of newcoming LNB remote control standards, an analogic modulation input pin is available (EXTM). An appropriate DC blocking capacitor must be used to couple the modulating signal source to the EXTM pin. When external modulation is not used, the relevant pin can be left open. Two pins are dedicated to the overcurrent protection/monitoring: CEXT and OLF. The overcurrent protection circuit works dynamically: as soon as an overload is detected in either LNB output, the output is shut-down for a time toff determined by the capacitor connected between CEXT and GND. Simultaneously the OLF pin, that is an open collector diagnostic output flag, from HIGH IMPEDANCE state goes LOW. After the time has elapsed, the output is resumed for a time ton=1/15toff (typ.) and OLF goes in HIGH IMPEDANCE. If the overload is still present, the protection circuit will cycle again through toff and ton until the overload is removed. Typical ton+toff value is 1200ms when a 4.7F external capacitor is used. This dynamic operation can greatly reduce the power dissipation in short circuit condition, still ensuring excellent power-on start up even with highly capacitive loads on LNB outputs. The device is packaged in PowerSO-20 for surface mounting. When a limited functionality in a smaller package matches design needs, a range of cost-effective PowerSO-10 solutions is also offered. All versions have built-in thermal protection against overheating damage.
a. External components are needed to comply to level 2.x and above (bidirectional) DiSEqCTM bus hardware requirements. DiSEqCTM is a trademark or EUTELSAT.
