Overview

Intended for analog and digital dual satellite receiver/Sat-TV, Sat-PC cards, the LNBH26LS is a monolithic voltage regulator and IC interface, assembled in QFN24 (4x4 mm) specifically designed to provide the 13/18 V power supply and the 22 kHz tone signaling to the LNB downconverter in the antenna dishes or to the multiswitch box. In this application field, it offers a complete solution for dual tuner satellite receivers with extremely low component count, low power dissipation together with simple design and I²C standard interfacing.

Applications

STB satellite receivers
TV satellite receivers
PC card satellite receivers

Key features

Complete interface between then LNB and I²C bus
Built-in DC-DC converter for single 12 V supply operation and high efficiency (typ. 93% @ 0.5A)
Selectable output current limit by external resistor
Compliant with main satellite receiver output voltage specification (8 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 high efficiency step-up PWM with integrated power NMOS allowing low power losses
Overload and overtemperature internal protection with I²C diagnostic bits
LNB short-circuit dynamic protection
+/-4 kV ESD tolerant on output power pins
