MP2174C  
2.7V-5.5V,4A, High-Efficiency,  
Synchronous Step-Down  
Converter with Forced CCM in 2×2mm QFN  
DESCRIPTION  
FEATURES  
The MP2174C is a monolithic, step-down,  
switch mode converter with built-in, internal  
power MOSFETs. It achieves 4A of continuous  
output current from a 2.7V to 5.5V input voltage  
with excellent load and line regulation. The  
output voltage can be regulated as low as 0.6V.  
Forced PWM Mode Operation  
Wide 2.7V to 5.5V Operating Input Range  
Output Voltage as Low as 0.6V  
4A Output Current  
35mΩ and 18mΩ Internal Power MOSFET  
Peak Efficiency Above 96%  
1.1MHz Frequency  
The constant-on-time (COT) control scheme  
provides fast transient response and easy loop  
stabilization.  
100% Duty Cycle in Dropout  
0.5ms Internal Soft-Start Time  
EN and Power Good for Power Sequencing  
Auto-Discharge at Power-Off  
Short-Circuit Protection with Hiccup Mode  
Available in a QFN-12 (2mmx2mm)  
Package  
Fault  
condition  
protections  
include  
cycle•by•cycle current limit and thermal  
shutdown.  
The MP2174C requires a minimal number of  
readily  
available,  
standard  
external  
components, and is available in an ultra-small  
QFN-12 (2mmx2mm) package.  
APPLICATIONS  
Storage Drives  
Portable/Handheld Devices  
Low-Voltage I/O System Power  
The MP2174C is ideal for a wide range of  
applications,  
including  
PDAs,  
portable  
instruments, DVD drives, and small handheld  
devices.
