SGM6014
1.4MHz, 2A Synchronous
Step-Down Converter
GENERAL DESCRIPTION
FEATURES
The SGM6014 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 while still achieving
over 95% efficiency during peak load conditions. The
SGM6014 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 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.
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 -40to +85
temperature 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.
