LM20144MHX/NOPB TI Power Management IC | 16-HTSSOP | 4.5V-5.5V Input, 4A Output

Product Overview

The LM20144MHX/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-lead HTSSOP package with exposed pad for enhanced thermal performance, this device operates from an input voltage range of 4.5V to 5.5V and delivers up to 4A of continuous output current. With an integrated 30mΩ high-side and 15mΩ low-side MOSFET, the LM20144 achieves excellent efficiency up to 95%. The switching frequency is adjustable from 500kHz to 1.5MHz, allowing optimization between efficiency and solution size. Protection features include overcurrent, overvoltage, and thermal shutdown.
