SGM6011
1.4MHz, 2A Synchronous
Step-Down Converter
GENERAL DESCRIPTION
FEATURES
The SGM6011 is a high efficiency monolithic synchronous
step-down regulator using 1.4MHz constant frequency,
current mode architecture. The device is available in an
adjustable version. It is ideal for portable equipment
requiring very high current up to 2A from single-cell Li-ion
batteries.
The SGM6011 also can run at 100% duty cycle for low
dropout operation, extending battery life in portable
systems while light load operation provides very low output
ripple for noise sensitive applications. It can supply up to
2A output load current from a 2.5V to 5.5V input voltage
and the output voltage can be regulated as low as 1.2V.
The high switching frequency (1.4MHz) minimizes the size
of external components while keeping switching losses low.
The internal slope compensation setting allows the device
to operate with smaller inductor values to optimize size and
provide efficient operation.
The SGM6011 is available in Green TDFN-3×3-10L
package and is rated over the -40to +85temperature
range.

OVERSTRESS CAUTION
Stresses beyond those listed may cause permanent damage to
the device. Functional operation of the device at these or any
other conditions beyond those indicated in the operational
section of the specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
reliability.
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.
Failure to observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performance degradation to complete 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.
DISCLAIMER
SG Micro Corp reserves the right to make any change in circuit
design, specification or other related things if necessary without
notice at any time.
