MP2116  
2A, 6V, 100% Duty Cycle Synchronous  
Step-Down Converter with 0.5A LDO  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2116 is an internally compensated  
1.25MHz, 2A synchronous step-down switching  
DC-DC converter plus a standalone low-input  
voltage, 0.5A low dropout (LDO) linear regulator.  
It is ideal for powering portable equipment that  
operates from a single cell Lithium-Ion (Li+)  
Battery. The MP2116 can provide up to 2A to  
the switcher output, and 0.5A load current to  
the LDO output from a 2.5V to 6V input voltage.  
Both output voltages can be regulated as low  
as 0.6V.  
100% Duty Cycle Low Dropout Operation  
(High-Side PFET)  
2A Switcher Output Current at VIN=3V  
Internal Power MOSFET Switches  
Stable with Ceramic Capacitors  
Up to 95% Efficiency for Switcher  
1.25MHz Switching Frequency  
Internal Soft-start for Switcher  
2.5V to 6V Input Range, for Switcher  
1V to VIN1 Input Range, for LDO  
0.5A LDO Output Current  
1μA Shutdown Current  
Thermal Shutdown  
Cycle-by-Cycle Over Current Protection  
Short Circuit Protection  
Power OK Output  
The 2A Synchronous switcher features  
integrated high-side and low-side switch for  
high efficiency and small footprint. With peak  
current mode control and internal compensation,  
the MP2116 is stable with ceramic capacitors.  
Fault condition protection includes cycle-by-  
cycle current limiting and thermal shutdown.  
Available in 10-Pin QFN Package  
APPLICATIONS  
The standalone low-input voltage 0.5A LDO is  
used to power noise sensitive circuitry. The  
LDO’s separate input supply pin (IN2) can be  
connected to the switcher output to reduce  
power dissipation and noise from the main  
switcher.
