TC7660HEOAG4 Product Details
The TC7660HEOAG4 is a pin-compatible replacement for the Industry standard TC7660HEOAG4 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 EMI. The on-board oscillator operates at a nominal frequency of 10kHz.Operation below 10kHz (for lower supply current applications)is possible by connecting an external capacitor from OSC to ground (with pin 1 open). The TC7660HEOAG4 is available in both 8-pin DIP and 8-pin SOIC packages in commercial and extended temperature ranges.
