TPS549B22RVFT TI DC-DC Converter | 40-LQFN-CLIP(7X5) | 4.5V-20V Input, 0.6V-5.5V Output

Product Overview

The TPS549B22RVFT from Texas Instruments is a high-performance, synchronous step-down DC-DC converter designed for space-constrained and power-dense applications. Housed in a compact 40-pin LQFN-CLIP package (7x5 mm), this device integrates MOSFETs and offers exceptional efficiency and thermal performance. With an input voltage range of 4.5V to 20V and an output voltage adjustable from 0.6V to 5.5V, it delivers up to 9A continuous output current. The TPS549B22RVFT features advanced modulation schemes, including D-CAP3™ control for fast transient response, and supports both forced continuous conduction mode (FCCM) and power-saving mode (PSM) for optimized efficiency across load ranges.
