TC3682/TC3683/TC3684

Inverting Charge Pump Voltage Doublers with Active Low Shutdown  
Features  
General Description  
• Small 8-Pin MSOP Package  
• Operates from 1.8V to 5.5V  
• 120 Ohms (typ) Output Resistance  
• 99% Voltage Conversion Efficiency  
• Only 3 External Capacitors Required  
• Power-Saving Shutdown Mode  
• Low Active Supply Current  
The TC3682/TC3683/TC3684 are CMOS charge pump  
converters that provide an inverted doubled output  
from a single positive supply. An on-board oscillator  
provides the clock and only three external capacitors  
are required for full circuit implementation. Switching  
frequencies 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.  
- 95µA (typ) for TC3682  
- 225µA (typ) for TC3683  
Low output source impedance (typically 120Ω), pro-  
vides output current up to 10mA. The TC3682/TC3683/  
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: generation of -7.2V from a +3.6V lithium  
cell or -10V generated from a +5V logic supply).  
- 700µA (typ) for TC3684  
• Fully Compatible with 1.8V Logic Systems  
Applications  
• LCD Panel Bias  
• Cellular Phones PA Bias  
• Pagers  
The minimum external part count, small physical size  
and shutdown mode feature make this family of prod-  
ucts useful for a wide variety of negative bias power  
supply applications.  
• PDAs, Portable Data Loggers  
• Battery-Powered Devices
