MP38874  
8A, 21V, 600KHz Step-Down Converter  
with Synchronizable Gate Driver  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP38874 is a monolithic step-down switch  
mode converter with a built in internal power  
MOSFET. It achieves 8A continuous output  
current over a wide input supply range with  
excellent load and line regulation.  
Wide 4.5V to 21V Operating Input Range  
8A Continuous Output Current  
42mInternal Power MOSFET Switch  
Power Good Indicator  
Synchronous Gate Driver Delivers up to  
95% Efficiency  
Current mode operation provides fast transient  
response and eases loop stabilization.  
Fixed 600KHz Frequency  
Synchronizable to >1MHz External Clock  
Cycle-by-Cycle Over Current Protection  
Thermal Shutdown  
Output Adjustable from 0.8V to 15V  
Stable with Low ESR Output Ceramic  
Capacitors  
Fault condition protection includes cycle-by-cycle  
current limiting and thermal shutdown.  
The MP38874 requires a minimum number of  
readily available standard external components  
and is available in a space saving 3mm x 4mm  
14-pin QFN package.  
Available in a 3mm x 4mm 14-Pin QFN  
Package
