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 lowcost 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 …
