MP2207  
16V, 4A, 1.3MHz Synchronous  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
4A Output Current  
The MP2207 is an internally compensated  
1.3MHz fixed frequency PWM synchronous  
step-down regulator with a 3V to 6V bias supply  
(VCC). MP2207 operates from a 3V to 16V input  
and generates an adjustable output voltage  
from 0.8V to 0.9xVIN at up to 4A load current.  
Input Supply Range: 3V to 16V  
80mInternal Power MOSFET Switches  
All Ceramic Output Capacitors Design  
Up to 95% Efficiency  
1.3MHz Fixed Switching Frequency  
Adjustable Output from 0.8V to 0.9xVIN  
Internal Soft-Start  
Frequency Synchronization Input  
Thermal Shutdown  
Cycle-by-Cycle Current Limiting  
Hiccup Short Circuit Protection  
10-lead, 3mm x 3mm QFN and SOIC8E  
Packages.  
The MP2207 integrates an 80mhigh-side  
switch and an 80msynchronous rectifier for  
high efficiency without an external Schottky  
diode. With peak current mode control and  
internal compensation, it is stable with a output  
ceramic capacitor and a small inductor. Fault  
protection  
includes  
hiccup  
short-circuit  
protection, cycle-by-cycle current limiting and  
thermal shutdown. Other features include  
frequency synchronization and internal soft-  
start.  
APPLICATIONS  
µP/ASIC/DSP/FPGA Core and I/O Supplies  
Printers and LCD TVs  
Network and Telecom Equipment  
Point of Load Regulators  
The MP2207 is available in small 3mm x 3mm  
10-lead QFN and SOIC8E packages.
