TPS53353DQPT TI Step-Down Regulator | 22-LSON-CLIP (6x5) | 4.5V-15V Input, 3A Output

Product Overview

The TPS53353DQPT is a high-efficiency, synchronous step-down (buck) regulator from Texas Instruments. It features a D-CAP3™ control mode for fast transient response and is designed for low output voltage ripple. The device operates from a 4.5V to 15V input voltage range and delivers up to 3A continuous output current. Housed in a compact 22-pin LSON-CLIP package (6mm x 5mm), it integrates both high-side and low-side MOSFETs, minimizing external component count and solution size.
