Monolithic Power Systems MP28258

Description

The MP28258 is a fully-integrated, highefficiency,synchronous, step-down, switch mode converter. It offers a very compact solution that can achieve a 3A continuous output current over a wide input supply range with excellent load and line regulation, and can operate at high efficiency over a wide outputcurrent load range.Constant-On-Time (COT) control mode provides fast transient response and eases loop stabilization.Full protection features include SCP, OCP, OVP, UVP and, thermal shut down.The MP28258 requires a minimal number of readily-available standard external components.This device is available in a space saving 2mmx3mm 12-pin QFN package.
