General Description
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 1
μA
(typ) of supply current.
Low output source impedance (typically 120
Ω), 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).
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.
