LM20154MHE/NOPB TI Step-Down Regulator | 16-HTSSOP | 3A, 1MHz

Product Overview

The LM20154MHE/NOPB is a high-performance, synchronous step-down (buck) regulator from Texas Instruments, designed to deliver up to 3A of continuous output current. It operates over a wide input voltage range of 2.95V to 5.5V, making it suitable for low-voltage systems powered by 3.3V or 5V rails. The device integrates high-side and low-side MOSFETs, achieving excellent efficiency up to 95%. With a fixed switching frequency of 1MHz, it allows for small external components, reducing board space. The LM20154MHE/NOPB is available in a 16-pin HTSSOP package with an exposed pad for enhanced thermal performance.
