Designed for analog and digital satellite receivers, the TPS65233 is a monolithic voltage regulator with I2C interface, specifically 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 to the multi-switch box. It offers a complete solution with very low component count, low power dissipation together with simple design and I2C standard interfacing.
TPS65233 features high power efficiency. The boost converter integrates a 120-mΩ power MOSFET running at 500-kHz switching frequency. Drop out voltage at the linear regulator is 0.8 V to minimize power loss. TPS65233 provides multiple ways to generate the 22-kHz signal. Integrated linear regulator with push-pull output stage generates clean 22-kHz tone signal superimposed at the output even at zero loading. Current limit of linear regulator can be programmed by external resistor with ±10% accuracy. Full range of diagnostic read by I2C is available for system monitoring.
The part is available in a 16-pin QFN 3-mm × 3-mm (RTE) package.
