A8286
A8286 is Dual LNB Supply and Control Voltage Regulator manufactured by Allegro MicroSystems.
Dual LNB Supply and Control Voltage Regulator
Features and Benefits
- 2-wire serial I2C™ -patible interface: control (write) and status (read)
- LNB voltages (16 programmable levels) patible with all mon standards
- Tracking switch-mode power converter for lowest dissipation
- Integrated converter switches and current sensing
- Output current limit of 900 mA typical, with 48 ms timer
- 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
