Inverting Charge Pump Voltage Doublers with Active Low Shutdown  
FEATURES  
GENERAL DESCRIPTION  
■ Small 8-Pin MSOP Package  
■ Operation from 1.8V to 5.5V  
The TC3682, TC3683 and TC3684 are CMOS charge  
pump converters that provide an inverted doubled output  
from a single positive supply. An on-board oscillator pro-  
vides the clock and only three external capacitors are  
required for full circuit implementation. Switching frequen-  
cies are 12kHz for the TC3682, 35kHz for the TC3683, and  
125kHz for the TC3684. When the SHDN pin is held at a  
logic low, the device goes into a very low power mode of  
operation consuming less than 1µA(typ.) of supply current.  
Low output source impedance (typically 120Ω), pro-  
vides output current up to 10mA. The TC3682, TC3683 and  
TC3684 feature a 1.8V to 5.5V operating voltage range and  
high efficiency, which make them an ideal choice for a wide  
variety of applications requiring a negative doubled voltage  
derived from a single positive supply (for example: genera-  
tion of -7.2V from a +3.6V lithium cell or –10V generated  
from a +5V logic supply).  
■ 120 Ohms (typ.) Output Resistance  
■ 99% Voltage Conversion Efficiency  
■ Only 3 External Capacitors Required  
■ Power-Saving Shutdown Mode  
■ Low Active Supply Current  
......................... 95µA (typ.) for TC3682  
..........................225µA (typ.) for TC3683  
..........................700µA (typ.) for TC3684  
■ Fully Compatible with 1.8V Logic Systems  
TYPICAL APPLICATIONS  
■ LCD Panel Bias  
■ Cellular Phones PA Bias  
■ Pagers  
■ PDAs, Portable Data Loggers  
■ Battery Powered Devices  
The minimum external parts count, small physical size,  
and shutdown mode make this family of products useful for  
a wide variety of negative bias power supply applications.
