Overview

Designed for analog and digital satellite receivers, the TPS65235 is a monolithic voltage regulator with I²C interface; specifically to provide the 13-V to 18-V power supply and the 22-kHz tone signal to the LNB down converter in the antenna dish or to the multiswitch box. It offers a complete solution with minimum component count, low power dissipation together with simple design and I²C standard interface. TPS65235 features high power efficiency. The boost converter integrates a 140-mΩ power MOSFET running at 1 MHz or 500 kHz selectable switching frequency. Drop out voltage at the linear regulator is 0.8 V to minimize power loss. TPS65235 provides multiple ways to generate the 22 kHz signal. Integrated linear regulator with push-pull output stage generates 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. TPS65235 supports advanced DiSEqC 2.x standard with 22-kHz tone detection circuit and output interface.
