The MP8757 is a fully-integrated, high frequency, synchronous, rectified, step-down converter. It offers a very compact solution to achieve a 7A output current over a wide input-supply range with excellent load and line regulation. MP8757 employs the Constant-On-Time (COT) control scheme, which provides fast transient response, eases loop stabilization. The COT control scheme provides seamless transition to PFM mode at light load operation which boosts the light load efficiency. Under voltage lockout is internally set as 4.5V. An open drain power good signal indicates output voltage is within its nominal voltage range. Full protection features include OCP, OVP, and thermal shut down. MP8757 requires minimum number of external components and are available in QFN21 (3mmx4mm) package.
