LM3478QMM/NOPB TI Switching Controller | 8-VSSOP | 2.97V-40V, 1A

Product Overview

The LM3478QMM/NOPB is a high-performance switching controller from Texas Instruments, designed for boost, flyback, and SEPIC topologies. It operates over a wide input voltage range of 2.97V to 40V and delivers up to 1A output current. Housed in a compact 8-VSSOP package, this device integrates a 40V, 1A N-channel MOSFET switch, making it ideal for space-constrained power supply designs. The LM3478 features current-mode control for fast transient response and cycle-by-cycle current limiting. Its low shutdown current (<1µA) enhances battery-powered applications.
