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. The

SP6661

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

碌SOIC

packages.
