GENERAL DESCRIPTION
The SGM6602 is a boost converter integrated with both
the PWM switch and the isolation switch. This device
accepts an input voltage range of 1.8V to 5.5V. And the
output voltage can reach a maximum of 20V. The
output of this device has the 9V or 12V default output
voltage when the FB pin is connected to VIN pin. This
device has a switching current limit of 900mA (TYP). It
is highly efficient with peak efficiency of 85% at 3.6V
input and 12V output when in operation. In shutdown
mode, the input and output are truly disconnected.
This device is targeted at the applications with high
voltage and small solution size requirements. The
1.1MHz switching frequency allows this device to use
small external components. The packages of this
device also allow it to have a tiny solution size. The
protection features involve the output short-circuit
protection, output over-voltage protection and thermal
shutdown.
The SGM6602 is available in Green WLCSP-0.8×1.2-6B
and TDFN-2×2-6L packages. It operates over an
ambient temperature range of -40℃ to +85℃.

OVERSTRESS CAUTION
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
This integrated circuit can be damaged if ESD protections are
not considered carefully. 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 even small parametric changes could cause the
device not to meet the published specifications.
