Overview

The TPA725x is a highly integrated solution for SMPS (Switching mode power supply) applications requiring voltage and current control loop.

The device integrates two op amps with open-drain output, a 1.21-V voltage reference, and a lower voltage reference for low-side current sensing circuit.

The device has a 200-μA supply current, which can be used in low-power applications.
