LM5642XMT/NOPB TI Dual Synchronous Buck Controller | 28-TSSOP | 4.5V-36V Input, 2% Accuracy

Product Overview

The LM5642XMT/NOPB is a high-performance dual synchronous buck controller from Texas Instruments, designed for efficient voltage regulation in demanding applications. It operates over a wide input voltage range of 4.5V to 36V and provides two independent outputs with ±2% accuracy over line, load, and temperature. The device features programmable switching frequency up to 1MHz, soft-start, and overcurrent protection. Housed in a 28-pin TSSOP package, it is ideal for space-constrained designs requiring high power density.
