SGM3204
Unregulated 200mA
Charge Pump Voltage Inverter
GENERAL DESCRIPTION
FEATURES
The SGM3204 is a charge pump voltage inverter that is
● Input Voltage Range: 1.4V to 5.5V
designed for operating over an input voltage range of
● Inverts Input Supply Voltage
1.4V to 5.5V. The SGM3204 can provide up to 200mA
● Output Current: 200mA
output current. The typical conversion efficiency
● Quiescent Current: 1.5mA (TYP)
exceeds 80% over a wide range of output current. The
● Switching Frequency: 950kHz
wide supply voltage is well suited for various
● Integrated Active Schottky Diode for Startup into
Load
applications powered by a 1-cell Li-Ion battery, as well
● -40℃ to +85℃ Operating Temperature Range
as 2-cell or 3-cell NiCd, NiMH or Alkaline batteries.
The shutdown current is less than 1μA. This device
● Available in a Green SOT-23-6 Package
requires one flying capacitor and two small bypass
capacitors for a complete charge pump inverter,
making it ideal for numerous battery-powered and
board level applications.
APPLICATIONS

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.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.
