The NCP3163 is a 3.4 A, 50 to 300 kHz step-up/down/inverting switching regulator that can be used in step-down, step-up, or voltage-inverting applications. This controller was specifically designed to be incorporated in step-down, step-up, or voltage-inverting applications with a minimum number of external components.
The NCP3163 is a monolithic power switching regulator optimized for DC‑DC converter applications, supporting step‑up, step‑down, and voltage‑inverting topologies with minimal external components. It targets cost‑sensitive consumer products as well as automotive, computer, and industrial markets.
The datasheet details the device’s key features such as a 3.4 A switch current, adjustable frequency from 50 kHz to 300 kHz, and an exposed‑pad package for enhanced thermal performance. Electrical characteristics, pin descriptions, maximum ratings, and package dimensions are provided for design reference.
