Introduction

AI Translation

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 downconverter 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.
