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 DiSEqCTM

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

Description

Intended for analog and digital satellite receivers,

the LNBP is a monolithic linear voltage regulator,

assembled in PowerSO-20 and PowerSO-10,

specifically designed to provide the powering

voltages and the interfacing signals to the LNB

downconverter situated in the antenna

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).
