MP2122  
6V, 2A, Low Quiescent Current  
Dual, SYNC Buck Regulator  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2122 is an internally-compensated,  
1MHz fixed-frequency, dual PWM, synchronous,  
step-down regulator. The MP2122 operates  
from a 2.7V-to-6V input, generates an output  
voltage as low as 0.608V, and has a 45µA  
quiescent current that makes it ideal for  
powering portable equipment that runs on a  
single cell lithium-ion (Li+) battery.  
Dual 2A-Output Current  
>93% Peak Efficiency  
>80% Light-Load Efficiency  
Wide 2.7V-to-6V Operating Input Range  
80mand 35mInternal Power MOSFET  
1MHz Fixed Switching Frequency  
Adjustable Output from 0.608V to VIN  
180° Phase-Shifted Operation  
100% Duty-Cycle Operation  
The MP2122 integrates dual 80mhigh-side  
switches and 35msynchronous rectifiers for  
high efficiency without an external Schottky  
diode. Peak-current mode control and internal  
compensation limits the minimum number of  
readily-available external components.  
45µA Quiescent Current  
Cycle-by-Cycle Over-Current Protection  
Short-Circuit Protection with Hiccup Mode  
Thermal Shutdown  
Available in an 8-pin TSOT23-8 Package  
Fault-condition protections include cycle-by-cycle  
current limiting and thermal shutdown.  
APPLICATIONS  
Small/Handhold Devices  
DVD Drivers  
Portable Instruments  
Smartphones and Feature Phones  
Battery-Powered Devices  
The MP2122 is available in an 8-pin TSOT23-8  
package.  
All MPS parts are lead-free and adhere to the RoHS directive. For MPS green  
status, please visit MPS website under Quality Assurance.
