LM3151MH-3.3/NOPB TI DC-DC Controller | 14-HTSSOP | 3.3V Output, 42V Input

Product Overview

The LM3151MH-3.3/NOPB is a high-performance, easy-to-use synchronous step-down DC-DC controller from Texas Instruments. It is designed to provide a regulated 3.3V output from a wide input voltage range of 6V to 42V. Housed in a compact 14-HTSSOP package, this controller integrates high-side and low-side MOSFET drivers, enabling efficient power conversion for a variety of applications. With its constant on-time (COT) control architecture, the LM3151 offers fast transient response and minimal external components, making it ideal for space-constrained designs.
