LM3475MF/NOPB TI DC-DC Controller | SOT-23-5 | 2.97V-5.5V, 1A

Product Overview

The LM3475MF/NOPB is a high-performance, current-mode, step-down (buck) DC-DC controller from Texas Instruments. It is designed to regulate output voltages as low as 0.8V with input voltages ranging from 2.97V to 5.5V. Housed in a compact SOT-23-5 package, this controller is ideal for space-constrained applications requiring efficient power conversion. The device features a fixed 550kHz switching frequency, enabling small external components while maintaining high efficiency.
