Texas Instruments  TPS65235-1EVM-747

The TPS65235-1EVM-747 evaluation module (EVM) is a fully assembled and tested circuit for evaluating the TPS65235-1 for DisEqC1.x applications. The EVM contains input and output connectors as well as control jumpers to ease evaluation of device features. The TPS65235-1 is a monolithic voltage regulator with I2C interface. It is specifically designed to provide the 13 V / 18 V power supply and the 22 kHz tone signaling to the LNB down-converter in the antenna dish or the multi-switch box.
