    Key features
    Key features
    • +/- 4 kV ESD tolerant on output power pins
    • LNB short circuit dynamic protection
    • Overload and over-temperature internal protections with I²C diagnostic bits
    • Low-drop post regulator and high efficiency step-up PWM with integrated power N-MOS allow low power losses
    • Complete interface between LNBS and I²C bus
    • Selectable output current limit by external resistor
    • Built-in DC-DC converter for single 12 V supply operation and high efficiency (typ. 93%@0.5 A)
    • Auxiliary modulation input (EXTM) facilitates DiSEqC™ 1.X encoding
    • Output voltage and output current level diagnostic feedback by I²C bits
    • Compliant with main satellite receivers output voltage specification
