Intended for analog and digital satellite receivers/Sat-TV and Sat-PC cards, the LNBH25 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 signalling 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 and low power dissipation together with a simple design and I²C standard interfacing.

  • 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 receivers output voltage specification (15 programmable levels)
  • Accurate built-in 22 kHz tone generator suits widely accepted standards
  • 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
  • LPM function (low power mode) to reduce dissipation
  • Overload and overtemperature internal protections with I²C diagnostic bits
  • LNB short-circuit dynamic protection
  • +/- 4 kV ESD tolerant on output power pins
