LM3153MHE-3.3/NOPB TI DC-DC Controller | 14-HTSSOP | 3.3V Output, 42V Input

Product Overview

The LM3153MHE-3.3/NOPB is a synchronous step-down (buck) DC-DC controller from Texas Instruments, designed to deliver a fixed 3.3V output with high efficiency. It operates from an input voltage range of 6V to 42V, making it suitable for a wide variety of applications. The device is housed in a 14-pin HTSSOP package with an exposed pad for enhanced thermal performance. It features constant on-time (COT) control architecture, which provides fast transient response and simplifies loop compensation. The LM3153MHE-3.3/NOPB is part of TI's Power Management portfolio and is RoHS compliant.
