MP8794GLE-P

MP8794 is a fully integrated, high frequency, synchronous, buck converter. It offers a compact solution that achieves up to 20A of output current with excellent load and line regulation over a wide input supply range. MP8794 operates at high efficiency over a wide output current load range. The device adopts an internally compensated constant-on-time control mode that provides fast transient response and eases loop stabilization. Output voltage start-up ramp is controlled by an internal 1ms timer that can be increased by adding a capacitor on REF/TRK. An open drain power good (PGOOD) signal indicates whether the output is within its nominal voltage range. PGOOD is clamped at about 0.7V with an external pull-up voltage when input supply fails to power the MP8794. It is available in a QFN-21 package. Applications include FPGAs, flat-panel televisions and monitors, multi-functional printers, access points, routers and optical modules. MPL-AY1265 inductor series matches best performance.
