LM20144MH/NOPB TI Power Management IC | 16-HTSSOP | 4A, 1MHz Step-Down Regulator

Product Overview

The LM20144MH/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 integrates a low RDS(on) MOSFET and operates at a fixed 1MHz switching frequency, enabling small external components. With an input voltage range of 2.95V to 5.5V, it provides an adjustable output voltage down to 0.8V with ±1.5% accuracy over line, load, and temperature. The LM20144MH/NOPB features cycle-by-cycle current limit, thermal shutdown, and output overvoltage protection, making it a robust solution for demanding industrial and telecom systems.
