ME7660 Charge Pump DC-DC Voltage Converter 
Data Sheet
Introduction
ME7660 is a charge pump DC-to-DC voltage converter using AL-gate CMOS technology and optimization design. It converters a +1.5V to +10V input to a corresponding -1.5V to -10V output using only two external capacitors, eliminating inductors and their associated cost, size and EMI. The on-board oscillator operates at a nominal frequency of 10KHZ. Operation below 10 KHZ (for lower supply current applications) is possible by connecting an external capacitor from OSC to ground.
Features:
- Converts +5V Logic supply to +/- 5V
- Wide input voltage range: 1.5V~10V
- Efficient voltage conversion: 99.9%
- Good power efficiency: 98%
- Low power supply: 50uA @5Vin
- Easy to use: only two external capacitors required
- 8-pin DIP and 8-pin small outline packages are available
- Compatible with RS232 negative power supply standard
- High ESD protection: up to 3kV
- No Dx diode needed for high voltage operation
