The ICL7660ACBAZA is a CMOS Voltage Converter. The ICL7660A monolithic CMOS power supply circuits which offer unique performance advantages over previously available devices. The ICL7660 performs supply voltage conversions from positive to negative for an input range of +1.5 to +10.0V resulting in complementary output voltages of -1.5 to -10.0V and the ICL7660A does the same conversions with an input range of +1.5 to +12.0V resulting in complementary output voltages of -1.5 to -12.0V. Only 2 noncritical external capacitors are needed for the charge pump and charge reservoir functions. The ICL7660A can also be connected to function as voltage doublers and will generate output voltages up to +18.6V with a +10V input.
The TC7660EOA is a charge pump DC-to-DC Voltage Converter for RS-232 negative power supply. The TC7660 device is a pin-compatible replacement for the industry standard 7660 charge pump voltage converter. It converts a +1.5 to +10V input to a corresponding -1.5 to -10V output using only two low-cost capacitors, eliminating inductors and their associated cost, size and electromagnetic interference (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.
