DESCRIPTION

The SP6661 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 -5.0V output can be converted from a +1.5V to +5.0V input. As a Voltage Doubler, a +5.0V to +10.0V output can be provided from a +2.5V to +5.0V input. TheSP6661 is ideal for both battery-powered and board level voltage conversion applications with a typical operating current of 3mA and a high efficiency (>90) over most of its load-current range. Typical end products for this device are disk drive supplies, operational amplifier and interface power supplies, medical instruments, and hand held and laptop computers. The SP6661 is available in 8-pin NSOIC, and µSOIC packages.
