TPS65235
Overview
Designed for analog and digital satellite receivers, the TPS65235 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 multiswitch box. It offers a complete solution with minimum component count, low power dissipation together with simple design and I2C standard interface.
