TPS54354MPWPREP TI Switching Regulator | 16-HTSSOP | 4.5-28V Input, 3A Output

Product Overview

The TPS54354MPWPREP is a high-performance, 3A synchronous step-down (buck) converter from Texas Instruments, designed for rugged industrial and automotive applications. It operates over a wide input voltage range of 4.5V to 28V and provides an adjustable output voltage down to 0.8V with high efficiency. Housed in a 16-pin HTSSOP package with PowerPAD for enhanced thermal performance, this device integrates low RDS(on) MOSFETs and features frequency synchronization, power-good output, and overcurrent protection. The enhanced product (EP) version ensures reliability in harsh environments, making it suitable for mission-critical systems.
