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
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.
