SGM6601
Low-Power DC-DC Step-Up Converter
GENERAL DESCRIPTION
The SGM6601 is a high-frequency boost converter
dedicated for small to medium LCD bias supply and white
LED backlight supplies. The device is ideal to generate
output voltages up to 38V from a dual cell NiMH/NiCd or
a single cell Li-ion battery. The part can also be used to
generate standard 3.3V/5V to 12V power conversions.
The SGM6601 operates with a switching frequency up to
1MHz. This allows the use of small external components
using ceramic as well as tantalum output capacitors.
Together with the small package, the SGM6601 gives a
very small overall solution size. The SGM6601 has an
internal 400mA switch current limit, offering low output
voltage ripple and allows the use of a small form factor
inductor for low power applications. The low quiescent
current (20μA TYP) together with an optimized control
scheme, allows device operation at very high efficiencies
over the entire load current range.
The SGM6601 is available in TDFN-2×2-6L and
TSOT-23-5 packages. It operates 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
the latest datasheet.
