MP2303A  
3A, 28V, 360kHz Synchronous Rectified  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2303A is a monolithic synchronous  
buck regulator. The device integrates a 150m  
high-side MOSFET and a 80mlow-side  
MOSFET that provide 3A continuous load  
current over a wide operating input voltage of  
4.7V to 28V. Current mode control provides fast  
transient response and cycle-by-cycle current  
limit.  
3A Output Current  
Wide 4.7V to 28V Operating Input Range  
Integrated MOSFET Switches  
Output Adjustable from 0.80V to 25V  
Up to 95% Efficiency  
Programmable Soft-Start  
Stable with Low ESR Ceramic Output Capacitors  
Fixed 360kHz Frequency  
Cycle-by-Cycle Over Current Protection  
Input Under Voltage Lockout  
Available in thermally enhanced 8-Pin SOIC  
and PDIP-8 packages  
An adjustable soft-start prevents inrush current  
at turn-on. In shutdown mode, the supply  
current drops to lower than 1μA.  
This device, available in an 8-pin SOIC and  
PDIP-8 packages, provides a very compact  
system solution with minimal reliance on  
external components.  
APPLICATIONS  
Distributed Power Systems  
Pre-Regulator for Linear Regulators  
Notebook Computers  
All MPS parts are lead-free and adhere to the RoHS directive. For MPS green  
status, please visit MPS website under Products, Quality Assurance page.
