产品概述

描述

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.

  • 所有功能

    • +/- 4 kV ESD tolerant on output power pins
    • LNB short circuit dynamic protection
    • Overload and over-temperature internal protections with I²C diagnostic bits
    • Low-drop post regulator and high efficiency step-up PWM with integrated power N-MOS allow low power losses
    • Complete interface between LNBS and I²C bus
    • Selectable output current limit by external resistor
    • Built-in DC-DC converter for single 12 V supply operation and high efficiency (typ. 93%@0.5 A)
    • Auxiliary modulation input (EXTM) facilitates DiSEqC™ 1.X encoding
    • Output voltage and output current level diagnostic feedback by I²C bits
    • Compliant with main satellite receivers output voltage specification
