MP8795HGLE-P

MP8795H is a fully integrated, high frequency, synchronous, buck converter. It offers a very compact solution that achieves up to 20A of output current with excellent load and line regulation over a wide input supply range. The MP8795H operates at high efficiency over a wide output current load range. It adopts an internally compensated constant-on-time (COT) control mode that provides fast transient response and eases loop stabilization. The operating frequency can be set to 600KHz, 800KHz or 1000KHz easily with MODE pin configuration, allowing the MP8795H frequency to remain constant regardless of the input and output voltages. The output voltage start-up ramp is controlled by an internal 1ms timer and can be increased by adding a capacitor on REF/TRK. An open drain power good signal indicates if output is within its nominal voltage range or not. Applications include FPGAs, flat-panel televisions and monitors, multi-functional printers, access points, routers and optical modules.
