Product overview

Description

Intended for analog and digital satellite receivers/Sat-TV and Sat-PC cards, the LNBH29 series is a monolithic voltage regulator and interface IC, assembled in QFN16 (3x3) and QFN16 (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 dish or to the multi-switch box. In this application field, it offers a complete solution with extremely low component count, low power dissipation together with a simple design and I²C standard interfacing.
  • All features

    • 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 specifications
    • Accurate built-in 22 kHz tone generator suits widely accepted standards
    • EXTM pin, auxiliary 22 kHz modulation input (LNBH29E) extends design flexibility
    • 22 kHz tone waveform integrity guaranteed also at no load condition
    • Low-drop post regulator and high efficiency step-up PWM with integrated power N-MOS allowing low power losses
    • Overload and overtemperature internal protection with I²C diagnostic bits
    • LNB short-circuit dynamic protection
    • +/- 4 kV ESD tolerant on output power pins
