    TC7662ACPA Product overview

    The TC7662ACPA is a charge pump DC-to-DC Converter for process instrumentation. The TC7662A is a pin-compatible upgrade to the industry standard TC7660 charge pump voltage converter. It converts a +3 to +18V input to a corresponding -3 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 (3 to 18V versus 1.5 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.

    .
    No external diodes required
    .
    Low output impedance at IL = 20mA, 40R typical
    .
    No low-voltage terminal required
    .
    CMOS construction
    ESD sensitive device, take proper precaution while handling the device.
