Description

The SP682  is a monolithic charge pump voltage converter that produces a doubled, negativevoltage from a single positive supply. The SP682 charge pump outputs a 10V voltage froma +5V input.  Three external charge pump capacitors are required to support the voltageconversion and voltage doubling process.  An internal oscillator generates a 12kHz clockwhich cycles the internal switching that charges the storage and transfer capacitors.  Thecharge 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 batterysource such as a lithium cell.  Typical applications are handheld instruments, notebook andlaptop computers, cellular phones, and data acquisition or GP systems. The  SP682  ispackaged in either 8-pin NSOIC, 8-pin MSOP for surface mount applications, and 8 Pin PDIP.
