MP38876  
10A, 28V, High Frequency Step-Down  
Converter with Synchronous Gate Driver  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP38876 is a monolithic step-down switch  
mode converter with a built in internal power  
MOSFET. It achieves 10A continuous output  
current over a wide input supply range with  
excellent load and line regulation.  
Wide 4.5V to 28V Operating Input Range  
10A Output Current  
18mInternal Power MOSFET Switch  
Synchronous Gate Driver Delivers up to  
95% Efficiency  
Synch from 300HKz to > 1MHz External Clock  
Synch Output to Drive Another Regulator in  
Phase-Shift Operation  
Default 600KHz / 1.2MHz Switching Frequency  
Feedback Voltage Accuracy: 1.5%  
Programmable Soft-Start  
Current mode operation provides fast transient  
response and eases loop stabilization.  
Fault condition protection includes cycle-by-cycle  
current limiting and thermal shutdown.  
The MP38876 requires a minimum number of  
readily available standard external components  
and is available in a 20-pin 3mm x 4mm QFN  
package.  
Startup Tracking  
EN and Power Good for Power Sequencing  
Cycle-by-Cycle Over Current Protection  
Thermal Shutdown  
Output Adjustable from 0.8V to 15V  
Stable with Low ESR Output Ceramic  
Capacitors  
The MP38876 is ideal for a wide range of  
applications including distributed power systems,  
pre-regulator for linear regulators, compact DC-  
DC regulators for PCB space limited platforms.  
Available in a 3mm x 4mm QFN Package
