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 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 be low 10kHz (for lower supply current applications) is also possible by connecting an external capacitor from OSC to ground.
