Description
General part information
TPS65235 Series
Designed for analog and digital satellite receivers, the TPS65235-1 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 TPS65235-1 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. The TPS65235-1 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 TPS65235-1 has a special design at FCCM mode to avoid the audible noise especially when VIN is higher or closer to the VLNB output.
