General Description:
The TC682 is a CMOS charge pump converter that
provides an inverted doubled output from a single
positive supply. An on-board 12 kHz (typical) oscillator
provides the clock and only 3 external capacitors are
required for full circuit implementation.
Low output source impedance (typically
140
Ω),
provides output current up to 10 mA. The TC682 fea-
tures 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.
