TC2682/TC2683/TC2684  
M
Inverting Charge Pump Voltage Doublers  
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  
- 95µA (typ) for TC2682  
The TC2682/TC2683/TC2684 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 TC2682, 35kHz for the  
TC2683, and 125kHz for the TC2684.  
Low output source impedance (typically 120),  
provides output current up to 10mA. The TC2682/  
TC2683/TC2684 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).  
- 225µA (typ) for TC2683  
- 700µA (typ) for TC2684  
Applications  
• LCD Panel Bias  
• Cellular Phones PA Bias  
• Pagers  
The minimum external part count and small physical  
size make this family of products useful for a wide  
variety of negative bias power supply applications.  
• PDAs, Portable Data Loggers  
• Battery-Powered Devices
