MP8715

MP8715

100% Duty Cycle Synchronous 4A, 21V, 500kHz Step-Down Converter

Datasheet

Description

The MP8715 is a 500 kHz 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 120mΩ high-side switch and a 50mΩ 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. The MP8715 is available in a space saving 8-pin SOIC package with an exposed pad.
