GENERAL DESCRIPTION

The TC3682, TC3683 and TC3684 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 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.

Low output source impedance (typically 120Ω), pro-

vides output current up to 10mA. The TC3682, TC3683 and

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: genera-

tion of -7.2V from a +3.6V lithium cell or –10V generated

from a +5V logic supply).

The minimum external parts count, small physical size,

and shutdown mode make this family of products useful for

a wide variety of negative bias power supply applications.
