FEATURES
● Complete interface between LNBS 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
● Auxiliary modulation input (EXTM) facilitates DiSEqC™ 1.X encoding
● Low-drop post regulator and high efficiency step-up PWM with integrated power N-MOS allow low power losses
● Overload and over-temperature internal protections with I²C diagnostic bits
● Output voltage and output current level diagnostic feedback by I²C bits
● LNB short circuit dynamic protection
● +/- 4 kV ESD tolerant on output power pins
DESCRIPTION
