DESCRIPTION  
FEATURES  
The MP2101 is an internally compensated  
1.6MHz fixed-frequency PWM step-down  
switcher with a 200mA low dropout (LDO) linear  
regulator. It is ideal for portable equipment  
powered by a single cell Lithium-Ion (Li+)  
Battery. The MP2101 can provide 800mA and  
200mA of load current from a 2.5V to 6V input  
voltage. Both output voltages can be regulated  
as low as 0.6V.

Up to 100% Switcher Duty Cycle  
Thermal Shutdown  
Cycle-by-Cycle Over Current Protection  
Short Circuit Protection  
The 800mA output channel features an  
integrated high-side switch and synchronous  
rectifier for high efficiency without an external  
Schottky diode. With peak current mode control  
and internal compensation, the MP2101 can be  
stabilized with ceramic capacitors and small  
inductors. The high-side switch can maintain  
100% duty cycle in dropout condition.  
Power On Reset Output  
Available in 3x3 10-Pin QFN Packages

DVD+/-RW Drives  
Smart Phones  
PDAs  
Digital Cameras  
Portable Instruments  
The 200mA 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. Dropout voltage is 280mV under  
a 150mA load. Fault condition protection  
includes cycle-by-cycle current limiting and  
thermal shutdown.  
“MPS” and “The Future of Analog IC Technology” are Trademarks of Monolithic  
Power Systems, Inc.  
The MP2101 is available in small 3mm x 3mm  
10-pin QFN packages.
