The MP28248 is a fully-integrated, high-efficiency, 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. The MP28248 operates at high efficiency over a wide output-current load range.?Constant-On-Time control mode provides fast transient response and eases loop stabilization.?Full protective features include short-circuit protection, over-current protection, over-voltage protection, under-voltage protection, and thermal shutdown.?The MP28248 requires a minimal number of readily-available standard external components.?This device is available in a space-saving 2mmx3mm 12-pin QFN package.
