TPS65233-1RTET

The TPS65233-1 voltage regulator is designed to provide the 13-V/18-V power supply and the 22-kHz tone signaling to the LNB down-converter in analog and digital satellite receivers. It offers a complete integration solution for LNB and I2C, supporting 9-V and 12-V power bus, with up to 1000-mA accurate output current limit adjustable by an external resistor and I2C.

The TPS65233-1 voltage regulator has several applications. It is specifically designed to provide the 13-V/18-V power supply and the 22-kHz tone signaling to the LNB down-converter, with an I2C interface. It integrates a boost converter, a LDO, and a 22-kHz tone generator that serves as a LNB power supply. This solution complies with the DiSEqC 1.x standard with or without I2C interface. The output current can be precisely programmed by an external resistor. Additionally, there are five ways to generate the 22-kHz tone signal with or without I2C. The integrated boost features low Rdson MOSFET and internal compensation, and a fixed 1-MHz switching frequency is designed to reduce component size.

The package size of the TPS65233-1 is 3.7mm x 3.7mm x 0.35mm for TPS65233-1RTER and 2.1mm x 1.85mm x 0.35mm for TPS65233-1RTET.
