SGM6600
90% Efficient Synchronous
Step-Up Converter with 1.2A Switch
GENERAL DESCRIPTION
The SGM6600 is a 1.2MHz, constant frequency, current
mode, synchronous, step-up switching regulator. Its
output current can go as high as 75mA while using a
single-cell alkaline, and discharge it down to 0.9V. It can
also be used for generating 5V at 500mA from a 3.3V rail
or a Li-ion battery.
High switching frequency minimizes the sizes of inductor
and capacitor. Integrated power MOSFETs and internal
compensation make the SGM6600 simple to use and fit
the total solution in a compact space.
For light load current, the SGM6600 enters into the power
saving mode to maintain high efficiency. Antiringing
control circuitry reduces EMI concerns by damping the
inductor in discontinuous mode. The SGM6600 provides
true output disconnect and this allows VOUT to go to
zero volts during shutdown without drawing any current
from the input source.
The output voltage of SGM6600-ADJ can be
programmed by an external resistor divider, and that of
SGM6600-3.3/SGM6600-5.0 are fixed internally on the
chip. The device is available in SOT-23-6 package. It
operated over an ambient temperature range of -40to
+85.

NOTE:
Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. These
are stress ratings only, and functional operation of the device at
these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
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.
SGMICRO reserves the right to make any change in circuit
design, specification or other related things if necessary without
notice at any time. Please contact SGMICRO sales office to get
