LNBH26

Dual LNB supply and control IC with step-up and I2C interface
  • active 活性

Intended for analog and digital dual satellite receivers/Sat-TV, and Sat-PC cards, the LNBH26 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 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.

Key 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 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 protection with I²C diagnostic bits
  • LNB short-circuit dynamic protection
  • +/- 4 kV ESD tolerant on output power pins
