Description
The RT5047 is a highly integrated voltage regulator and interface IC, specifically design for supplying power and control signals from advanced satellite set-top box (STB) modules to the LNB down-converter in the antenna dish or to the multi-switch box.
Features
- Wide Input Supply Voltage Range : 8V to 16V.
- Output Current Limit of 550mA with 45ms timer.
- Low Noise LNB Output Voltage (13.3V and 18.3V
by SEL Pin, 14.3V and 19.3V by COMP Pin).
- 3% High Accuracy for 0mA to 500mA Current
Output.
- Push-Pull Output Stage minimizes 13.3V to
18.3V and 18.3V to 13.3V Output Transition Time.
- External 22kHz Tone Input.
- Meet DiSEqCTM1.x Protocol.
- Output Short Circuit Protection.
- Over-Temperature Protection.
