Charge Pump DC-DC Voltage Converter CE7660 Charge Pump DC-DC Voltage Converter CE7660 CE7660 is a charge pump dc-to-dc voltage converter using Si-gate CMOS technology and optimization design. It converters a +2.5V to +10V input to a corresponding -2.5V 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 • Wide input voltage range: 2.5V~10V • Efficient voltage conversion:99.
