25 pcs Micro Power Inverting Charge Pump
2.4V to 5.5V Input Range 8 Pin MSOP
The SP682 is a monolithic charge pump voltage converter that produces a doubled, negative
voltage from a single positive supply. The SP682 charge pump outputs a 10V voltage from
a +5V input. Three external charge pump capacitors are required to support the voltage
conversion and voltage doubling process. An internal oscillator generates a 12kHz clock
which cycles the internal switching that charges the storage and transfer capacitors. The
charge pump architecture is fabricated using a low power BiCMOS process technology.
The SP682 charge pump is ideal for low power applications requiring a typical +3V battery
source such as a lithium cell. Typical applications are handheld instruments, notebook and
laptop computers, cellular phones, and data acquisition or GP systems. The SP682 is
packaged in either 8-pin NSOIC, 8-pin MSOP for surface mount applications, and 8 Pin PDIP.
