    Key features
    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% at 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 for 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
    • RoHS compliant
