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 per channel and 750 mA total

? 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

? 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
