TC7662A
GENERAL DESCRIPTION
The TC7662A is a pin-compatible upgrade to the In-
dustry 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 addi-
tion 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 be-
low 10kHz (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 DIP packages in com-
mercial and extended temperature ranges.
