The TPS65233-1 from Texas Instruments is a monolithic voltage regulator designed for analog and digital satellite receivers. It integrates a complete solution for LNB power supply and I2C interface, including DiSEqC 1.x compatibility. This device provides 13-V/18-V power and 22-kHz tone signaling to the LNB down-converter in antenna dishes or multi-switch boxes.
Key electrical specifications include an input voltage range of 4.5V to 20V and a maximum output current of 1A, adjustable via external resistor and I2C. The device features a boost converter with a low 120-mΩ internal power MOSFET and a linear regulator with a low dropout voltage of 0.8V to minimize power loss. The current limit accuracy is within ±10%.
The TPS65233-1 operates within a temperature range of -40°C to 85°C. It is available in a 16-pin WQFN package measuring 3.00mm x 3.00mm. The regulator offers features such as LNB short circuit dynamic protection, diagnostics for output voltage, input supply, UVLO, and DiSEqC tone output, as well as cable disconnect diagnostics.
