SGM3209
High Voltage,
Charge Pump DC/DC Converter
GENERAL DESCRIPTION
FEATURES
The SGM3209 is a charge pump voltage converter
which is used to generate a negative supply from a
positive input. The 3V to 18V input voltage can be
converted into a corresponding -3V to -18V output
supply. The SGM3209 is also capable of delivering up
to 100mA of output current. The switching frequency is
resistor programmable from 120kHz to 1.25MHz. The
device also has the advantage of using a combination
of few external components to eliminate the inductors
and their associated cost, size and EMI.
● Input Voltage Range: 3V to 18V
● Output Current: 100mA
● Pull-Low Resistor on EN Pin: 600kΩ
● Programmable Oscillator Frequency: 120kHz to
1.25MHz
● No External Diodes Required
● Low Output Impedance: 15Ω (TYP) at IOUT = 20mA
● CMOS Construction
● -40℃ to +85℃ Operating Temperature Range
● Available in Green TDFN-2×2-8L and SOIC-8
Packages
The SGM3209 enters into shutdown status by external
enable control signal to reduce system power
dissipation. The device is used for design requirements
with higher output current and/or lower input/output
voltage drop.
APPLICATIONS
Laptop Computers
Disk Drives
The SGM3209 is available in Green TDFN-2×2-8L and
SOIC-8 packages. It operates over an ambient
temperature range of -40℃ to +85℃.

OVERSTRESS CAUTION
ABSOLUTE MAXIMUM RATINGS
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.

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.
RECOMMENDED OPERATING CONDITIONS
Input Voltage Range...............................................3V to 18V
Operating Temperature Range.......................-40℃ to +85℃
