GENERAL DESCRIPTION
The TC2682, TC2683 and TC2684 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 TC2682, 35kHz for the TC2683, and
125kHz for the TC2684.
Low output source impedance (typically 120
), pro-
vides output current up to 10mA. The TC2682, TC2683 and
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: genera-
tion of -7.2V from a +3.6V lithium cell or -10V generated from
a +5V logic supply).
The minimum external parts count and small physical
size make this family of products useful for a wide variety of
negative bias power supply applications.
