LM20154MH/NOPB TI Power Management IC | 16-HTSSOP | 4.5V-5.5V Input, 4A Output

Product Overview

The LM20154MH/NOPB is a high-performance, 4A step-down DC-DC converter from Texas Instruments, designed for point-of-load regulation in space-constrained applications. Housed in a 16-pin HTSSOP package, it offers excellent thermal performance and efficiency up to 95%. The device operates from an input voltage range of 4.5V to 5.5V and provides a regulated output voltage as low as 0.8V. With integrated power MOSFETs and a fixed switching frequency of 500kHz, the LM20154MH/NOPB minimizes external component count and simplifies design.
