SGM6610
10A Fully-Integrated
Synchronous Boost Converter
GENERAL DESCRIPTION
FEATURES
The SGM6610 is a high-efficient synchronous boost
converter. The 2.7V to 12V operation input voltage is
suitable for single-cell or two-cell Li-Ion batteries. This
device is capable to provide 10A switch current and an
output voltage range of 4.5V to 12.6V. The SGM6610
has two operation modes, the pulse width modulation
(PWM) mode and pulse frequency modulation (PFM).
The PWM mode is applied at moderate to heavy loads.
The PFM mode is applied at light load to improve the
efficiency. An adjustable switching frequency of 200kHz
to 2.2MHz can be operated in the PWM mode. The
protection features include output over-voltage
protection at 13.2V, cycle-by-cycle over-current
protection and thermal shutdown. The device also
involves the functions of programmable soft-start and
adjustable switch peak current limit.

ESD Susceptibility
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 SENSITIVITY CAUTION
HBM.............................................................................2000V
MM.................................................................................400V
CDM ............................................................................1000V
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.
