LNBH25LS Product details

Description

Intended for analog and digital satellite receivers/Sat-TV and Sat-PC cards, the LNBH25LS is a monolithic voltage regulator and interface IC, assembled in QFN24L (4x4 mm) specifically designed to provide 13/18 V power supply and 22 kHz tone signaling 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 receiver output voltage specifications (15 programmable levels).
Accurate built-in 22 kHz tone generator suits widely accepted standards.
22 kHz tone waveform integrity guaranteed at no-load condition.
Low drop post regulator and high eff.
