The MP8714 is a high-frequency, synchronous, rectified, step-down, switch-mode converter. This fully integrated solution achieves 10A of output current with excellent load and line regulation over a wide input supply range.
Current mode operation provides fast transient response and eases loop stabilization. EN/SYNC supports external clock synchronization, and an open-drain power good pin (PG) indicates when the output voltage is in the nominal range.
Full protection features include over-voltage protection (OVP), hiccup over-current protection (OCP), and thermal shutdown.
The MP8714 requires a minimal number of readily available, standard, external components and is available in a QFN-14 (3mmx4mm) package.

Evaluation KitGET THIS KIT
The EV8714-LE-00A is used for demonstrating the performance of MPS’s MP8714. MP8714 is a highly integrated and high frequency synchronous step-down switch-mode converter. It is optimized to support up to 10A load current over an input supply range from 4.5V to 17V with excellent load and line regulation.
Current-Mode operation provides fast transient response and eases loop stabilization.
EN/SYNC supports external clock synchronization, and an open-drain power good pin(PG) indicates when the output voltage is in the nominal range.
Full protection features include over voltage, hiccup over-current protection and thermal shut down.
The MP8714 is available in QFN-14(3mmx4mm) package.
