As a Voltage Inverter, a -1.5V to -4.25V output can be converted from a +1.5V to +4.25V input. As a Voltage Doubler, the SP6660 can provide a +8.0V output at 100mA from a +4.25V input. The SP6660 is ideal for both battery-powered and board level voltage conversion applications with a typical operating current of 400A and a high efficiency (>90%) over most of its load-current range. Typical end products for this device are operational amplifier and interface power supplies, medical instruments, and hand- held and laptop computers. The SP6660 is available in 8-pin DIP, SOIC, and SOIC packages. +V TYPICAL CIRCUIT: VOLTAGE INVERTER IN +1.5V to +4.25V TYPICAL CIRCUIT: VOLTAGE DOUBLER +V +V IN 1 FC 8 +1.5V to +4.25V +V DOUBLE FC 1 VOLTAGE 8 CAP+ OUTPUT SP6660 7 2 OSC CAP+ LV SP6660 GND 7 2 OSC C2 3 6 1F to 150F C1 GND 3 LV 1F to 150F 6 C1 CAP- OUT NEGATIVE 1F to 150F 5 4 VOLTAGE OUTPUT CAP- OUT 4 5 C2 1F to 150F SP6660DS/11 SP6660 200mA Charge Pump Inverter or Doubler Copyright 2000 Sipex Corporation 1ABSOLUTE MAXIMUM RATINGS These are stress ratings only and functional operation of the OUT and V+ Continuous Output Current.....................250mA device at these ratings or any other above those indicated in the Output Short-Circuit Duration to GND.................................1s operation sections of the specifications below is not implied.
