SGM6011  
1.4MHz, 2A, Synchronous Buck Converter  
GENERAL DESCRIPTION  
FEATURES  
The SGM6011 is a high-efficient monolithic synchronous  
buck converter 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  
operate in the forced continuous pulse width  
modulation (PWM) mode. The SGM6011 is highly  
efficient with peak efficiency at 95% when in operation.  
The device could operate at 100% duty cycle to  
achieve the lowest dropout and longer battery life.  
2.5V to 5.5V Input Voltage Range  
Forced Continuous PWM Mode Operation  
Up to 95% High Efficiency  
1.4MHz Constant Frequency Operation  
2A Output Current  
100% Duty Cycle for Lowest Dropout  
Shutdown Current: 2µA (MAX)  
135mΩ Low RDS(ON) Internal Switches  
Support Ceramic Capacitors  
Current Mode Control for Excellent Line and  
Load Transient Responses  
Internal Soft-Start Protection  
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.  
Short Circuit and Thermal Protection  
-40to +85Operating Temperature Range  
Available in a Green TDFN-3×3-10L Package  
APPLICATIONS  
The SGM6011 is available in Green TDFN-3×3-10L  
package and is rated over the -40to +85℃  
temperature range.

FB/OUT, SW Voltages..............................-0.3V to VIN + 0.3V  
Power Dissipation, PD @ TA = +25  
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

ESD Susceptibility  
ESD SENSITIVITY CAUTION  
This integrated circuit can be damaged if ESD protections are  
not considered carefully. 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 even small parametric changes could cause the  
device not to meet the published specifications.
