Description
General part information
MP8757 Series
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.Wide 5V to 18V Operating Input Range 7A Continuous Output Current Low RDS(ON) Internal Power MOSFETs Proprietary Switching Loss Reduction Technique Internal Soft Start Output Discharge 500kHZ Switching Frequency OCP, OVP, UVP Protection and Thermal Shutdown Latch off Reset via EN or Power Cycle Output Adjustable from 0.604V to 5.5V
