LNBH24L Dual LNBS supply and control IC with step-up and I²C interface 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-temperature internal protections with I²C diagnostic bits ■ Output voltage and output current level diagnostic feedback by I²C bits ■ LNB short circuit dynamic protection ■ +/- 4 kV ESD tolerant on output power pins 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. In this application field, it offers a dual tuner STBs complete solution with extremely low component count, low power dissipation together with simple design and I²C standard interfacing.
