Product details

Description

Intended for analog and digital satellite receivers/Sat-TV and Sat-PC cards, the LNBH25 is a monolithic voltage regulator and interface IC, assembled in QFN24 4x4 specifically designed to provide the 13/18 V power supply and the 22 kHz tone signalling to the LNB down-converter in the antenna dish or to the multi-switch box.

Features

Complete interface between LNB and I²C bus.
Built-in DC-DC converter for single 12 V supply operation and high efficiency (typ. 93 % @ 0.5 A).
Selectable output current limit by external resistor.
Compliant with main satellite receivers output voltage specification (15 programmable levels).
Accurate built-in 22 kHz tone generator suits widely accepted standards.
22 kHz tone waveform integrity guaranteed also at no load condition.
Low-drop post regulator and hi.
