SGM6010
3A, 2MHz, Synchronous Buck Converter
GENERAL DESCRIPTION
FEATURES
The SGM6010 is a synchronous, buck DC/DC converter
with a range of 3V to 5.5V input voltage. This device is
capable to provide a 3A continuous output current. It
operates with a programmable frequency range of
300kHz to 2MHz. The SGM6010 is highly efficient with
peak efficiency at 95% when in operation. The 100%
duty cycle could make the lowest dropout.
● 3V to 5.5V Input Voltage Range
● Up to 95% High Efficiency
● 120mΩ Low RDS(ON) Internal Switches
● 300kHz to 2MHz Programmable Frequency
● 3A Output Current
● 0.8V Reference Allows Low Output Voltages
● Shutdown Current: 2μA (MAX)
● 100% Duty Cycle for Lowest Dropout
● Forced Continuous PWM Mode Operation
● No External Power MOSFETs and Schottky Diode
Required
The forced continuous pulse width modulation (PWM)
mode operation could decrease the ripple voltage to
the lowest level and reduce noise and RF interference
as well. No external power MOSFETs and Schottky
diode are required because of the internal synchronous
low on-resistance power switches. The external
compensation can improve the transient response
across the loads and output capacitors.
● Excellent Line and Load Transient Responses
● -40℃ to +85℃ Operating Temperature Range
● Available in a Green TDFN-3×3-10L Package
The SGM6010 is available in a Green TDFN-3×3-10L
package. It is rated over the -40℃ to +85℃ temperature
range.

ESD Susceptibility
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.
