Product Descriptions
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.
