TPS544B20RVFT TI DC-DC Converter | 40-LQFN-CLIP(7X5) | 4.5V-18V Input, 20A Output

Product Overview

The TPS544B20RVFT 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 4.5V to 18V input voltage range and provides an adjustable output voltage down to 0.6V. Housed in a compact 40-pin LQFN-CLIP package (7mm x 5mm), this device integrates MOSFETs and features PMBus interface for telemetry and configuration. With excellent efficiency and thermal performance, it is ideal for space-constrained power systems requiring high current density.
