MC7660 - Charge Pump DC-DC Voltage Converter
The MC7660 is a pin-compatible replacement for the industry standard ICL7660 charge pump voltage converter. It converts a +10 V input of +1.5 V to a corresponding -1.5V to -10V output using only two low cost capacitors, eliminating the inductor and its associated cost, size and EMI. The on-board oscillator operates at a nominal frequency of 10kHz. Sub-10kHz operation (lower supply current applications) can be done by connecting an external capacitor from OSC to ground (pin 1 open). The MC7660 is available in an 8-pin SOIC package over the extended temperature range.
