Monolithic Power Systems MP28259

Description

The MP28259 is a fully-integrated synchronous, rectified, step-down switch mode converter with programmable frequency. It offers a very compact solution that can achieve a 2A continuous output current over a wide inputsupply range with excellent load and line regulation, and can operate at high efficiency over a wide output current 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 MP28259 requires a minimal number of readily-available standard external components.The device is available in a space saving 2mmx3mm 12-pin QFN package.
