MP28373  
3A, 28V, 1.4MHz  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP28373 is a 1.4MHz step-down regulator  
with a built-in power MOSFET. It achieves 3A  
continuous output current over a wide input  
supply range with excellent load and line  
regulation.  
3A Continuous Output Current, 4A Peak  
Output Current  
Programmable Soft-Start  
100mInternal Power MOSFET Switch  
Stable with Low ESR Output Ceramic  
Capacitors  
Up to 91% Efficiency  
20μA Shutdown Mode  
Fixed 1.4MHz Frequency  
Thermal Shutdown  
Current mode operation provides fast transient  
response and eases loop stabilization.  
Fault condition protection includes cycle-by-  
cycle current limiting and thermal shutdown.  
Adjustable soft-start reduces the stress on the  
input source at turn-on. In shutdown mode, the  
regulator draws 20μA of supply current.  
Cycle-by-Cycle Over Current Protection  
Wide 4.75V to 28V Operating Input Range  
Output is Adjustable From 0.92V to 21V  
Under Voltage Lockout  
The MP28373 is available in an 8-pin SOIC  
package with an exposed pad, and requires a  
minimum number of readily available external  
components to complete a 3A step-down DC to  
DC converter solution.  
APPLICATIONS  
Distributed Power Systems  
Battery Chargers  
Pre-Regulator for Linear Regulators
