TPS544B20RVFR TI DC-DC Converter | 40-LQFN-CLIP (7X5) | 4.5V-18V Input, 20A Output

Product Overview

The TPS544B20RVFR is a high-performance, non-isolated DC-DC converter from Texas Instruments, designed to deliver up to 20A of continuous output current. It operates from a wide input voltage range of 4.5V to 18V, making it suitable for a variety of intermediate bus and point-of-load applications. The device integrates a 20A MOSFET with a low RDS(on) to achieve high efficiency and compact design. Housed in a 40-pin LQFN-CLIP package (7mm x 5mm), it offers excellent thermal performance and space savings.
