The Texas Instruments TPS65235-1RUKR is a versatile LNB voltage regulator designed for satellite receiver applications. It integrates a boost converter and a linear (LDO) regulator, providing a complete solution for LNB power. The device supports an input voltage range of 4.5V to 20V and offers adjustable output voltages between 11V and 20V.
A key feature is its I2C interface, which allows for control and configuration, including adjustable current limits up to 1000 mA. The TPS65235-1RUKR operates with selectable switching frequencies of 500 kHz or 1 MHz and has a typical switch current limit of 3A. It is designed for surface mount installation in a 20-WQFN (3x3 mm) package.
This regulator is suitable for applications requiring precise voltage and current control for LNBs, supporting DiSEqC 2.x and 1.x standards. It includes diagnostic features for output voltage, current levels, and cable connections, along with thermal protection.
