The TC7660COA device is a pin-compatible replacement for the industry standard 7660 charge pump voltage converter. It converts a +1.5V to +10V input to a corresponding -1.5V to -10V output using only two low-cost capacitors, eliminating inductors and their associated cost, size and electromagnetic interference (EMI).

• Negative Supplies for Data Acquisition Systems and Instrumentation

The TC7660 charge pump converter inverts the voltage applied to the V+ pin. The conversion consists of a two-phase operation. During the first phase, switches S2 and S4 are open and switches S1 and S3 are closed. C1 charges to the voltage applied to the V+ pin, with the load current being supplied from C2. During the second phase, switches S2 and S4 are closed and switches S1 and S3 are open. A charge is transferred from C1 to C2, with the load current being supplied from C1.
