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