LM3677LEE-1.2/NOPB TI DC-DC Converter | 6-USON(2x1.5) | 1.2V Fixed Output, 600mA

Product Overview

The LM3677LEE-1.2/NOPB is a high-efficiency, step-down DC-DC converter from Texas Instruments, designed to deliver a fixed 1.2V output from a 2.7V to 5.5V input supply. Housed in a compact 6-pin USON package (2mm x 1.5mm), this device is ideal for space-constrained applications requiring low ripple and high efficiency. With a maximum load current of 600mA, it integrates synchronous rectification for improved efficiency and uses a pulse-width modulation (PWM) control scheme with automatic power-save mode at light loads.
