Product Description

The MP8715 is a 500kHz fixed-frequency PWM synchronous step-down regulator. MP8715 operates from a 4.5V to 21V input and generates an output voltage form 0.8V to VIN with 100% duty cycle operation.

The MP8715 integrates a 120m? high-side switch and a 50m? synchronous rectifier for high efficiency without an external Schottky diode. It offers a very compact solution to achieve 4A continuous output current over a wide input supply range with excellent load and line regulation.

External soft start and power good indication meet flexible design requirement.
