MP8795GLE-Z

MP8795 is a fully integrated, high frequency, synchronous, buck converter. It offers a very compact solution that achieves up to 15A of output current with excellent load and line regulation over a wide input supply range. The MP8795 adopts an internally compensated constant-on-time (COT) control mode that provides fast transient response and eases loop stabilization. The output voltage start-up ramp is controlled by an internal 1ms timer. It can be increased by adding a capacitor on SS. An open-drain power good (PGOOD) signal indicates if output is within its nominal voltage range. PGOOD is clamped at around 0.7V with an external pull-up voltage when input supply fails to power the MP8795. It requires a minimal number of readily available, standard, external components and is available in a QFN-21 (3mmx4mm) package. Applications include solid-state drives (SSD), flat-panel televisions and monitors, set-top boxes and distributed power systems.
