DESCRIPTION

The SP6660 is a CMOS DC-DC Monolithic Voltage Converter that can be implemented as a Voltage Inverter or a Positive Voltage Doubler. 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 SP6660can 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 400µA 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 handheld and laptop computers. The SP6660 is available in 8-pin DIP, SOIC, and µSOIC packages.
