MP28224  
1.5A Step-Down Switcher  
with Auxiliary 0.5A LDO  
The Future of Analog IC Technology  
FEATURES  
DESCRIPTION  
1.5A and 0.5A Outputs  
The MP28224 is an internally compensated  
1.5MHz fixed frequency PWM 1.5A step-down  
switcher with an auxiliary 0.5A low dropout  
(LDO) linear regulator. It is ideal for powering  
portable equipment that runs from a single cell  
Lithium-Ion (Li+) Battery. The MP28224 can  
provide 1.5A and 0.5A of load current from a  
2.5V to 6V input voltage. Both output voltages  
can be regulated as low as 0.6V.  
Internal Power MOSFET Switches  
Stable with Low ESR Output Ceramic  
Capacitors  
Up to 95% Efficiency  
1μA Shutdown Current  
1.5MHz Switching Frequency  
Thermal Shutdown  
Cycle-by-Cycle Over Current Protection  
Short Circuit Protection  
Internal Soft-start for Switcher  
Power On Reset Output  
2.5V to 6V Input Range VIN1 for Switcher  
1.1V to VIN1 Input Range VIN2 for LDO  
Available in 10-Pin QFN Packages  
The 1.5A switcher features an integrated  
high-side switch and synchronous rectifier for  
high efficiency. With peak current mode control  
and internal compensation, the MP28224 can  
be stabilized with ceramic capacitors and small  
inductors. Fault condition protection includes  
cycle-by-cycle current limiting and thermal  
shutdown.  
APPLICATIONS  
DVD+/-RW Drives  
Smart Phones  
PDAs  
Digital Cameras  
Portable Instruments  
The auxiliary 0.5A LDO output is used to power  
noise sensitive circuitry. It has a separate input  
supply to reduce power dissipation and noise  
from the main switcher.  
MP28224 is available in the small 10-pin QFN  
packages.
