SGM6014  
1.4MHz, 2A Synchronous  
Buck Converter  
GENERAL DESCRIPTION  
FEATURES  
The SGM6014 is  
a
high-efficient monolithic  
2.5V to 5.5V Input Voltage Range  
Up to 95% High Efficiency  
1.4MHz Constant Frequency Operation  
2A Output Current  
3.3V Fixed and Adjustable Output Voltages  
100% Duty Cycle for Lowest Dropout  
Shutdown Current: 2µA (MAX)  
Low Quiescent Current: 55μA in PFM Mode  
135mΩ Low RDS(ON) Internal Switches  
Support Ceramic Capacitors  
synchronous buck regulator with a wide input voltage  
range of 2.5V to 5.5V. The device is available in a 3.3V  
fixed output and an adjustable voltage versions. This  
device is targeted at the portable equipment with high  
current requirements from single-cell Li-Ion batteries. It  
can enter pulse frequency modulation (PFM) (low IQ)  
mode with typically 55μA quiescent current for highest  
light load efficiency to maximize battery life.  
The SGM6014 could operate at 100% duty cycle to  
achieve the lowest dropout and longer battery life. This  
device is capable to provide up to 2A output load  
current and operates at a 1.4MHz constant frequency  
to achieve the smallest size of external components.  
The internal slope compensation allows the use of  
smaller-value inductors to give improved solution size  
to this device.  
Current Mode Control for Excellent Line and  
Load Transient Responses  
Internal Soft-Start Protection  
Short Circuit and Thermal Protection  
-40to +85Operating Temperature Range  
Available in a Green TDFN-3×3-10L Package  
APPLICATIONS  
SGM6014 is available in both adjustable and 3.3V fixed  
output voltage versions; in the Green TDFN-3×3-10L  
package. It is rated over the -40to +85℃  
temperature range.

OVERSTRESS CAUTION  
ABSOLUTE MAXIMUM RATINGS  
Stresses beyond those listed in Absolute Maximum Ratings  
may cause permanent damage to the device. Exposure to  
absolute maximum rating conditions for extended periods  
may affect reliability. Functional operation of the device at any  
conditions beyond those indicated in the Recommended  
Operating Conditions section is not implied.

ESD Susceptibility  
ESD SENSITIVITY CAUTION  
This integrated circuit can be damaged by ESD if you don’t  
pay attention to ESD protection. SGMICRO recommends that  
all integrated circuits be handled with appropriate precautions.  
Failureto observe proper handlingand installation procedures  
can cause damage. ESD damage can range from subtle  
performance degradation tocomplete device failure. Precision  
integrated circuits may be more susceptible to damage  
because very small parametric changes could cause the  
device not to meet its published specifications.
