Maxim Integrated (ICL7662CBA+) DC/DC Adjustable Charge Pump 4.5V to 20V

DC/DC Adjustable Charge Pump Voltage Converter, 4.5V to 20V in, -20V to -4.5V/20mA out, SOIC-8Product OverviewThe ICL7662CBA+ is a monolithic charge Pump Voltage Inverter for inexpensivenegative supplies. The pump voltage inverter that will convert a positivevoltage in the range of +4.5 to +20V to the corresponding negative voltage of-4.5 to -20V. The ICL7662 provides performance far superior to previousimplementations of charge pump voltage inverters by combining low quiescentcurrent with high efficiency. The ICL7662 has an oscillator, control circuitryand 4 power MOS switches on-chip, with the only required external componentsbeing two capacitors.Cascaded voltage multiplication99.70% Typical open circuit conversion efficiencyApplicationsTest & Measurement, Power ManagementProduct InformationOutput Type: AdjustableInput Voltage Min: 4.5VInput Voltage Max: 20VDC / DC Converter IC Case: SOICNo. of Pins: 8PinsOutput Current: 20mAAdjustable Output Voltage Min: -20VAdjustable Output Voltage Max: -4.5VTopology: InvertingOperating Temperature Max: 70°C
