TPS53313RGER TI Step-Down Regulator | 24-VQFN (4x4) | 3A, 4.5V-28V

Product Overview

The TPS53313RGER from Texas Instruments is a high-efficiency, synchronous step-down (buck) regulator designed for a wide input voltage range of 4.5V to 28V. It delivers up to 3A of continuous output current with excellent transient response. The device integrates low RDS(on) power MOSFETs and features a fixed 500kHz switching frequency, enabling compact power supply designs. Housed in a 24-pin VQFN (4x4mm) package, it is ideal for space-constrained applications requiring high power density.
