TC7660 IC – Charge Pump DC to DC Voltage Converter IC

The TC7660 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). The on-board oscillator operates at a nominal frequency of 10 kHz. Operation below 10 kHz (for lower supply current applications) is possible by connecting an external capacitor from OSC to ground. The TC7660 is available in 8-Pin PDIP, 8-Pin Small Outline (SOIC) and 8-Pin CERDIP packages in commercial and extended temperature ranges.
