General Description

• Available in 8-Pin PDIP and 8-Pin CERDIP

Packages

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.

Applications

• Laptop Computers

• Disk Drives

• Process Instrumentation

• P-based Controllers

Range

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.
