MP9403  
3A, 7V, 250kHz Integrated Synchronous  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP9403 is a monolithic synchronous buck  
regulator. The device integrates a 150m  
high-side MOSFET and a 100mlow-side  
MOSFET that provides 3A continuous load  
current over input voltage of 4.3V to 7V. Current  
mode control provides fast transient response  
and cycle-by-cycle current limit.  
3A Output Current  
4.3V to 7V Operating Input Range  
Integrated MOSFET Switches  
Output Adjustable from 0.80V to 5.50V  
Up to 93% Efficiency  
Programmable Soft-Start  
Stable with Low ESR Ceramic Output Capacitors  
Fixed 250kHz Frequency  
Cycle-by-Cycle Over Current Protection  
Input Under Voltage Lockout  
Thermally Enhanced 8-Pin SOIC Package  
An adjustable soft-start prevents inrush current  
at turn-on. In shutdown mode, the supply  
current drops to 1μA.  
This device, available in an 8-pin SOIC  
package with exposed pad, provides a very  
compact system solution with minimal reliance  
on external components.
