TPS543C20RVFT TI DC-DC Converter | 40-LQFN-CLIP (7x5) | 4.5V-18V Input, 20A Output

Product Overview

The TPS543C20RVFT from Texas Instruments is a high-performance, synchronous step-down DC-DC converter designed for space-constrained and power-dense applications. It integrates MOSFETs and supports up to 20A continuous output current. The device operates over a wide input voltage range of 4.5V to 18V, making it suitable for a variety of intermediate bus and point-of-load (POL) designs. Housed in a compact 40-pin LQFN-CLIP package (7mm x 5mm), it offers excellent thermal performance and low EMI.
