产品描述

The MP1493 is a fully integrated, high–efficiency 3A synchronous rectified step-down converter. The MP1493 operates at high efficiency over a wide output current load range. Adaptive Constant-On-Time (COT) control mode provides fast transient response, eases loop stabilization, and operates with a low-cost electrolytic capacitor.  The MP1493 requires a minimum number of readily available standard external components and is available in an 8-pin SOIC ROHS compliant package.
