LM3477MMX/NOPB TI Switching Controller | 8-VSSOP | 2.97V-5.5V, 1A

Product Overview

The LM3477MMX/NOPB is a high-performance current-mode PWM buck controller from Texas Instruments, designed for step-down (buck) regulator applications. It operates from an input voltage range of 2.97V to 5.5V and can deliver output currents up to 1A. The device features a fixed 500kHz switching frequency, integrated high-side N-channel MOSFET driver, and a precision 1.26V reference. Housed in an 8-pin VSSOP package, it offers a compact solution for space-constrained power designs.
