FEBRUARY 2014 – REV. A
GENERAL DESCRIPTION
The SGM6601 is a high-frequency boost converter. The
input voltage accepts a range of 1.8V to 5.5V. It is
specified for small to medium LCD bias supply and
white LED backlight supplies. The switching frequency
can reach up to 1MHz, which supports both ceramic
output capacitors and tantalum output capacitors.
The internal 400mA switch current limit provides a low
output voltage ripple. For low-power applications, this
device allows the use of a small form factor inductor. A
typical low quiescent current of 20μA together with an
optimized control scheme allows the device to achieve
very high efficiency over the whole load current.
The adjustable output voltage can reach a maximum of
38V ideally with a dual cell NiMH/NiCd battery or a
single cell Li-ion battery. And a standard 3.3V/5V to 12V
power conversion can also be achieved.
The SGM6601 is available in TDFN-2×2-6L and
TSOT-23-5 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.
