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
beprovidedfroma+2.5Vto+5.0Vinput.TheSP6661isidealforbothbattery-poweredandboard
levelvoltageconversionapplicationswithatypicaloperatingcurrent of3mAandahighefficiency
(>90%) over most of its load-current range. Typical end products for this device are disk drive
supplies, operationalamplifierandinterfacepowersupplies, medicalinstruments, andhandheld
and laptop computers. The SP6661 is available in 8-pin NSOIC, and µSOIC packages.

Optimizing Capacitor Selection
RefertoFigure1forthetotaloutputresistanceforvariouscapacitancevaluesandoscillatorfrequencies.
The reservoir and charge pump capacitor values are equal. The capacitance values required to maintain
comparable ripple and output resistance typically diminish proportionately as the pump frequency of
the SP6661 increases.
