RT5007
Single Output LNB Power Supply Controller with I2C Interface
General Description
The RT5007 is a highly integrated voltage
regulator and interface IC, specifically designed for supplying power and control signals from advanced satellite Set-Top Box (STB) modules to the Low Noise Block (LNB) down converter in the antenna dish or to the multi-switch box.
The device consists of an independent current-mode Boost controller and low a dropout linear
regulator and the circuitry required for 22kHz tone generation to support one-way DiSEqCTM communications.
All the functions and the LNB output voltages (8 programmable levels) can be controlled via the I2C bus.
The RT5007 has fault signal t...
