SA24481
Description
The SA2448x is a high efficiency synchronous step-down DC-DC converter capable of delivering a load current of 1A/3A. It operates over a wide input voltage range of 4.5V to 36V and integrates main and synchronous MOSFET switches with very low RDS(ON) to minimize conduction loss.
Key Features
