RT5047A Description
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...
