Designed for analog and digital satellite receivers, the TPS652353 is a monolithic voltage regulator with I 2C 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 multi-switch box. The device offers a complete solution with minimum component count, low power dissipation together with simple design and I 2C standard interface.

The TPS652353 features high-power efficiency. The boost converter integrates a 140-mΩ power MOSFET running at 1-MHz or 500-kHz selectable switching frequency. Dropout voltage at the linear regulator is 0.8 V to minimize power loss. The TPS652353 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 I 2C is available for system monitoring.

The TPS652353 has a special design at forced PWM mode to avoid the audible noise especially when VIN is higher or closer to the VLNB output.

The TPS652353 supports advanced DiSEqC 2.x standard with 22-kHz tone detection circuit and output interface.
