(*1): Mounted on glass epoxy board. (76.2×114.3×1.6mm:based on EIA/JDEC standard, 2Layers)

(*2): Mounted on glass epoxy board. (76.2×114.3×1.6mm:based on EIA/JDEC standard, 4Layers,internal Cu area: 74.2×74.2mm)

(*3): Connecting any input terminal to voltages greater than V+ or less than GND may cause destructive latchup. It is recommended that

no inputs from sources operating from external supplies be applied prior to “power-up” of the NJU7660A

 INPUT VOLTAGE RANGE

V+=1.5V to 10V (for Negative Voltage Converter)

V+=3.0V to 10V (for Twofold Voltage Converter)
