MP8795

MP8795 16V, 15A, Synchronous, Step-Down Converter with Adjustable Current Limit, Programmable Frequency DESCRIPTION The MP8795 is a fully integrated, highfrequency, 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 operates at high efficiency over a wide output current load range. The MP8795 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 configuration, allowing the MP8795 frequency to remain constant regardless of the input and output voltages. 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 the output is within its nominal voltage range. PGOOD is clamped at around 0.7V with an external pull-up voltage when the input supply fails to power the MP8795. Full protection features include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and overtemperature protection (OTP). The MP8795 requires a minimal number of readily available, standard, external components and is available in a QFN-21 (3mmx4mm) package.
