  • Intended for analog and digital dual satellite receivers/Sat-TV, and Sat-PC cards, the LNBH26S is a monolithic voltage regulator and interface IC, assembled in QFN24 4x4 specifically designed to provide the 13/18 V power supply and the 22 kHz tone signaling to the LNB down-converter in the antenna dishes or to the multi-switch 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.

    主要特性

    • Complete interface between LNB 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 receiver output voltage specification (15 programmable levels)
    • Accurate built-in 22 kHz tone generator suits widely accepted standards
    • 22 kHz tone waveform integrity guaranteed at no-load condition as well
    • Low drop post regulator and high efficiency step-up PWM with integrated power NMOS allowing low power losses
    • LPM function (low power mode) to reduce dissipation
    • Overload and overtemperature internal protection with I²C diagnostic bits
    • LNB short-circuit dynamic protection
    • +/- 4 kV ESD tolerant on output power pins
