LM3677LEE-1.5/NOPB TI DC-DC Converter | 6-USON(2x1.5) | 1.5V Fixed Output, 600mA

Product Overview

The LM3677LEE-1.5/NOPB is a high-efficiency, step-down DC-DC converter from Texas Instruments, designed to deliver a fixed 1.5V output with up to 600mA load current. Housed in a compact 6-pin USON package (2mm x 1.5mm), this device is ideal for space-constrained applications requiring low noise and high efficiency. With a wide input voltage range of 2.7V to 5.5V, it supports single-cell Li-Ion batteries and standard 3.3V/5V rails. The LM3677 features automatic PFM/PWM mode switching, ensuring high efficiency across the entire load range, and includes internal soft-start, over-current protection, and thermal shutdown.
