General Description
Designed for analog and digital satellite receivers, the TPS65235-1 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 multi-switch box.
Key Features
- Complete integrated solution for LNB and I2C interface.
- DiSEqC 2.x, and DiSEqC 1.x compatible.
- Supports 5-V, 12-V, and 15-V power rail.
- Up to 1000-mA accurate output current limit adjustable by external resistor.
- Boost switch peak current limit proportional to LDO current limit.
- Boost converter with 140-mΩ low Rds(on) internal power switch.
- Boost switching frequency 1-MHz or 500-kHz selectable.
- Audible noise avoided at forc.
