MP2117  
1.25MHz, 2.2A Synchronous  
Step-Down Switcher  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2117 is an internally compensated 2.2A  
synchronous step-down switcher. The operating  
frequency is internally set at 1.25MHz. MP2117  
is ideal for powering portable equipment that  
runs from a single cell Lithium-Ion (Li+) Battery.  
The MP2117 can provide up to 2.2A continuous  
load current from a 2.5V to 6V input voltage.  
The output voltage can be regulated as low as  
0.6V. 100% duty cycle provides low dropout  
operation that extends operating time in battery-  
operated systems.  
2.2A Output Current  
2.5V to 6V Input Range VIN  
Internal Power MOSFET Switches  
Low Dropout Operation: 100% Duty Cycle  
Up to 90% Efficiency  
Stable with Ceramic Output Capacitors  
1µA Shutdown Current  
1.25MHz Switching Frequency  
Thermal Shutdown  
Cycle-by-Cycle Over Current Protection  
Output Short Circuit Protection  
Internal Soft-start  
The MP2117 features an integrated high-side  
switch and synchronous rectifier for high  
efficiency. With peak current mode control and  
internal compensation, the MP2117 can be  
stabilized with ceramic capacitors and small  
inductors. Fault condition protection includes  
cycle-by-cycle current limiting and thermal  
shutdown.  
Power On Reset Output  
Available in 10-Pin QFN (3mmx3mm) and  
8-pin SOIC Packages  
APPLICATIONS  
DVD+/-RW Drives  
LCD TV  
PDAs  
MP2117 is available in the small 10-pin  
3mmx3mm QFN and SOIC-8 packages.
