LM20145MHE/NOPB TI Power Management IC | 16-HTSSOP | 4.5V-5.5V Input, 1A Output

Product Overview

The LM20145MHE/NOPB is a high-performance, synchronous step-down DC-DC converter from Texas Instruments, designed to deliver up to 1A of continuous output current. It operates from an input voltage range of 4.5V to 5.5V, making it ideal for point-of-load regulation in various systems. The device is housed in a compact 16-pin HTSSOP package with an exposed pad for enhanced thermal performance. With integrated power MOSFETs and a fixed 1.5MHz switching frequency, the LM20145MHE/NOPB provides a small solution size while maintaining high efficiency.
