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
● -40℃ to +85℃ Operating 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 -40℃ to +85℃
temperature range.

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.
