Features and Benefits
▪ 2-wire serial I2C™ -compatible interface: control (write) and
status (read)
▪ LNB voltages (16 programmable levels) compatible with
all common standards
▪ Tracking switch-mode power converter for lowest dissipation
▪ Integrated converter switches and current sensing
▪ Provides up to 500 mA load current
▪ Static current limit circuit allows full current at startup and
13→18 V output transition; reliably starts wide load range
▪ Push-pull output stage minimizes 13→18 V and 18→13 V
output transition times for highly capacitive loads
▪ Adjustable rise/fall time via external timing capacitor
▪ Built-in tone oscillator, factory-trimmed to 22 kHz
facilitates DiSEqC™ tone encoding, even at no-load
▪ Four methods of 22 kHz tone generation, via I2C™ data
bits and/or external pin
▪ Filter bypass MOSFET minimizes losses during tone transmit
▪ 22 kHz tone detector facilitates DiSEqC™ 2.0 decoding
▪ Auxiliary modulation input
▪ LNB overcurrent with timer
▪ Diagnostics for output voltage level, input supply UVLO,
and DiSEqC™ tone output
▪ Cable disconnect diagnostic
