产品概述
The RT5047A 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. The device is consists of the independent current-mode boost controller and low dropout linear regulator along with the circuitry required for 22KHz tone shaping to support DiSEqCTM1.x communications. The RT5047A has fault protection (over-current, over-temperature and under-voltage lockout).
- Wide input supply voltage range : 8V to 16V
- Output current limit of 550mA with 45ms timer
- Low noise LNB output voltage
- 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
