RT5006
Single Output LNB Power Supply Controller with I2C Interface
General Description
The RT5006 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 a low dropout linear regulator and the circuitry required for 22kHz tone generation and integrates tone detection capability, to support full one-way DiSEqCTM communications.
All the functions and the LNB output
voltages (16 programmable levels) can be controlle...
