MP8715  
100% Duty Cycle Synchronous  
4A, 21V, 500kHz Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
4A Output Current  
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.  
Wide 4.5V to 21V Input Operation Range  
100% Duty Cycle Support  
120m/50mInternal Power MOSFET  
All Ceramic Capacitor Design  
Up to 95% Efficiency  
500kHz Fixed Switching Frequency  
Adjustable Output from 0.8V to Vin  
External Soft-Start  
Frequency Synchronization Input  
Power OK Indicator  
The MP8715 integrates a 120mhigh-side  
switch and a 50msynchronous 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.  
Internal Compensation  
Over Current Hiccup and Thermal Protection  
Available in 8-pin SOIC Package with an  
Exposed Pad and 14-pin QFN3x4 package  
External soft start and power good indication  
meet flexible design requirement.  
APPLICATIONS  
Cable eMTAs  
µP/ASIC/DSP/FPGA Core and I/O Supplies  
Printers and LCD TVs  
The MP8715 is available in a space saving 8-  
pin SOIC package with an exposed pad and  
3mmx4mm 14-pin QFN package.  
Digital Set Top Boxes  
Network and Telecom Equipment  
Point of Load Regulators
