SA24404 Description
The SA24404 is a high efficiency synchronous step-down DC-DC regulator with internal power and synchronous rectifier switches. It operates using fixed frequency and peak current control over a wide input voltage range of 4V to 36V, and can deliver up to 4A of continuous output current. The SA24404 is specially designed with a symmetric QFN package and adjustable LX rise time to achieve good EMI performance.
