UCC3941N-5 TI DC-DC Controller | 8-PDIP | 5V Fixed Output, Step-Down

Product Overview

The UCC3941N-5 from Texas Instruments is a high-performance, fixed 5V output step-down (buck) DC-DC controller designed for low-power applications. Housed in an 8-pin PDIP package, it integrates all necessary control circuitry for efficient voltage regulation. With a wide input voltage range of 4.5V to 40V, it is ideal for industrial, automotive, and telecom systems requiring a stable 5V rail.
