Hot-selling and scarce TC7660EOA Charge Pump DC-to-DC Voltage Converter SOP8 spot stock

Product Descriptions

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.
