Renesas (ICL7660ACPAZ) DC/DC Adjustable Charge Pump Voltage Converter

DC/DC Adjustable Charge Pump Voltage Converter, 1.5V to 12V in, -12V to -1.5V/45mA out, DIP-8Product OverviewThe ICL7660ACPAZ is a CMOS Voltage Converter. The ICL7660A monolithic CMOS powersupply circuits which offer unique performance advantages over previouslyavailable devices. The ICL7660 performs supply voltage conversions from positiveto negative for an input range of +1.5 to +10.0V resulting in complementaryoutput voltages of -1.5 to -10.0V and the ICL7660A does the same conversionswith an input range of +1.5 to +12.0V resulting in complementary output voltagesof -1.5 to -12.0V. Only 2 noncritical external capacitors are needed for thecharge pump and charge reservoir functions. The ICL7660A can also be connectedto function as voltage doublers and will generate output voltages up to +18.6Vwith a +10V input.Simple conversion of +5V logic supply to ±5V suppliesSimple voltage multiplication VOUT = (-) nVINTypical open circuit voltage conversion efficiency 99.9%Typical power efficiency 98%Easy to use, requires only 2 external non-criticalPassive componentsNo external diode over full temperature and voltage rangeApplicationsPower ManagementProduct InformationOutput Type: AdjustableInput Voltage Min: 1.5VInput Voltage Max: 12VDC / DC Converter IC Case: DIPNo. of Pins: 8PinsOutput Current: 45mAAdjustable Output Voltage Min: -12VAdjustable Output Voltage Max: -1.5VTopology: Doubler, InvertingOperating Temperature Max: 70°CProduct Range: ICL7660S; ICL7660A
