LNBH24L Product details

Description

Intended for analog and digital DUAL satellite receivers/Sat-TV, Sat-PC cards, the LNBH24L is a monolithic voltage regulator and interface IC, assembled in QFN 5x5 ePAD, specifically designed to provide the 13 / 18 V power supply and the 22 kHz tone signaling for two independent LNB down-converters in the antenna dishes and/or multi-switch box.

Features

Complete interface between LNBS 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.
Auxiliary modulation input (EXTM) facilitates DiSEqC™ 1.X encoding.
Low-drop post regulator and high efficiency step-up PWM with integrated power N-MOS allow low power losses.
Overload and over-tempe.
