LM3370SD-4221/NOPB TI DC-DC Converter | 16-WSON (5X4) | 2.3MHz, 2A

Product Overview

The LM3370SD-4221/NOPB is a high-efficiency, dual-channel step-down DC-DC converter from Texas Instruments. It integrates two synchronous buck regulators with a 2.3MHz switching frequency, delivering up to 2A per channel. The device operates from an input voltage range of 2.7V to 5.5V, making it ideal for battery-powered and point-of-load applications. The compact 16-WSON (5x4mm) package enables space-constrained designs.
