TC1682/TC1683/TC1684  
M
Inverting Charge Pump Voltage Doublers with Active High 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 TC1682/TC1683/TC1684 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 TC1682, 35kHz for the  
TC1683, and 125kHz for the TC1684. When the SHDN  
pin is held at a logic high, the device goes into a very  
low power mode of operation consuming less than 1µA  
(typ) of supply current.  
- 95µA (typ) for TC1682  
- 225µA (typ) for TC1683  
Low output source impedance (typically 120Ω),  
provides output current up to 10mA. The TC1682/  
TC1683/TC1684 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 TC1684  
• Fully Compatible with 1.8V Logic Systems  
Applications  
• LCD Panel Bias  
• Cellular Phones PA Bias  
• Pagers  
• PDAs, Portable Data Loggers  
• Battery-Powered Devices  
The minimum external part count, small physical size  
and shutdown mode feature make this family of  
products useful for a wide variety of negative bias  
power supply applications.
