TPS544C20RVFT TI DC-DC Converter | 40-LQFN-CLIP (7X5) | 4.5V-18V Input, 20A Output

Product Overview

The TPS544C20RVFT is a high-performance, non-isolated DC-DC converter from Texas Instruments, designed for space-constrained and high-current applications. Housed in a compact 40-pin LQFN-CLIP package (7x5 mm), this device integrates a 20A continuous output current capability with an input voltage range of 4.5V to 18V. It features adaptive constant on-time (ACOT) control for fast transient response and excellent line/load regulation. The TPS544C20RVFT is ideal for powering FPGAs, ASICs, and processors in telecom, networking, and industrial systems.
