The SA24406E is a high efficiency synchronous step-down DC-DC regulator with internal power and synchronous rectifier MOSFETs. It operates using fixed frequency and peak current control over a wide input voltage range of 4V to 36V, and can deliver up to 6A of continuous output current.
The SA24406E is specially designed with a symmetric QFN package and adjustable LX rise time to achieve good EMI performance. The switching frequency can be adjusted from 300kHz to 2.2MHz, or synchronized to an external clock. The frequency can be selected to meet application EMI limits and to avoid noise in important frequency bands.
The SA24406E offers excellent efficiency over a wide range of applications by providing internal 41mΩ power and 21mΩ synchronous rectifier MOSFETs and an external bias input. The 1μA shutdown supply current allows the device to be used in battery powered applications. The SA24406E ensures safe operation in all operating conditions, providing cycle-by-cycle current limit, input undervoltage lockout, internal soft-start, output undervoltage and overvoltage protection, and thermal shutdown.
The SA24406E is available in a QFN3.5mm×4mm-14 pin package.
