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.
