TPS54478RTET TI DC-DC Converter | 16-WQFN (3x3) | 4.5V-18V Input, 4A Output

Product Overview

The TPS54478RTET is a high-performance, 4A synchronous step-down (buck) converter from Texas Instruments. It integrates high-side and low-side MOSFETs and operates over a wide input voltage range of 4.5V to 18V. The device features an adaptive on-time control architecture that provides fast transient response and stable operation with ceramic output capacitors. The TPS54478RTET is available in a compact 16-pin WQFN (3x3 mm) package, making it ideal for space-constrained applications.
