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