GENERAL DESCRIPTION
The TC682 is a CMOS charge pump converter that
provides an inverted doubled output from a single positive
supply. An on-board 12kHz (typical) oscillator provides the
clock and only 3 external capacitors are required for full
circuit implementation.
Low output source impedance (typically 140
), pro-
vides output current up to 10mA. The TC682 features low
quiescent current and high efficiency, making it the ideal
choice for a wide variety of applications that require a
negative voltage derived from a single positive supply (for
example: generation of – 6V from a 3V lithium cell or – 10V
generated from a +5V logic supply).
The minimum external parts count and small physical
size of the TC682 make it useful in many medium-current,
dual voltage analog power supplies.
