General Description
The TC7662A is a pin-compatible upgrade to the
industry standard TC7660 charge pump voltage
converter. It converts a +3V to +18V input to a
corresponding -3V to -18V output using only two low-
cost
capacitors,
eliminating
inductors
and
their
associated cost, size and EMI. In addition to a wider
power supply input range (3V to 18V versus 1.5V to
10V for the TC7660), the TC7662A can source output
currents as high as 40mA. The on-board oscillator
operates at a nominal frequency of 12kHz. Operation
below 12kHz (for lower supply current applications) is
also possible by connecting an external capacitor from
OSC to ground.
The TC7662A directly is recommended for designs
requiring greater output current and/or lower input/
output voltage drop. It is available in 8-pin PDIP and
CERDIP packages in commercial and extended
temperature ranges.
