Renesas (ICL7660CPAZ) DC/DC Adjustable Charge Pump Voltage Converter

DC/DC Adjustable Charge Pump Voltage Converter, 1.5V to 10V in, -10V to -1.5V/45mA out, DIP-8Product OverviewThe ICL7660CPAZ is a monolithic CMOS charge pump voltage converter in 8 leadNSOIC package. This monolithic CMOS power supply circuit offers uniqueperformance advantages. The ICL7660CPAZ performs supply voltage conversions frompositive to negative for an input range of 1.5V to 10.0V resulting incomplementary output voltages of -1.5V to -10.0V. Only two noncritical externalcapacitors are needed for charge pump and charge reservoir functions. TheICL7660CPAZ can also be connected to function as voltage doublers and willgenerate output voltages up to 18.6V with 10V input. It has on-chip series DCsupply regulator, RC oscillator, voltage level translator and four output powerMOS switches. A unique logic element senses most negative voltage in device andensures that output N channel switch source substrate junctions are not forwardbiased. This assures latch-up free operation. The oscillator when unloadedoscillates at a nominal frequency of 10KHz for an input supply voltage of 5V.Simple conversion of +5V logic supply to ±5V suppliesSimple voltage multiplication (VOUT = (-) nVIN)Typical open circuit voltage conversion efficiency of 99.9%Typical power efficiency of 98%No external diode required over full temperature and voltage rangeOperating temperature range from 0°C to 70°CApplicationsPower ManagementProduct InformationOutput Type: AdjustableInput Voltage Min: 1.5VInput Voltage Max: 10VDC / DC Converter IC Case: DIPNo. of Pins: 8PinsOutput Current: 45mAAdjustable Output Voltage Min: -10VAdjustable Output Voltage Max: -1.5VTopology: Doubler, InvertingOperating Temperature Max: 70°CProduct Range: ICL7660; ICL7660AMSL: MSL 1 - Unlimited
