A8293
Single LNB Supply and Control Voltage
Regulator
FEATURES AND BENEFITS
▪ 2-wire serial I2C™ -compatible interface: control (write) and status (read)
▪ LNB voltages (8 programmable levels) compatible with all common standards including domestic Japan models
▪ Tracking switch-mode power converter for lowest dissipation ▪ Integrated converter switches and current sensing ▪ Provides up to 700 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 timi...
