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)

CE7660 Features

* Wide input voltage range: 2.5V~10V

* Efficient voltage conversion:99.9%

* Good power efficiency: 98%

* Low power supply: 50uA @5V input

* Easy to use: only two external capacitors required

* Compatible with RS232 negative power supply standard
