Product Introduction

Overview

The TPS54620RGYT from Texas Instruments is a highly integrated, synchronous step-down converter designed for high-efficiency power management in compact designs. This device is housed in a thermally enhanced 3.50 mm x 3.50 mm QFN package, making it ideal for space-constrained applications. It operates with an input voltage range of 4.5V to 17V and can deliver up to 6A of output current, with an adjustable output voltage ranging from 0.8V to 15V. The TPS54620RGYT features integrated high-side and low-side MOSFETs, which enhances efficiency and reduces the overall component count and footprint of the power supply design.
