Description

This is a charge pump IC. It is used in several GuitarPCB projects to allow a PNP Germanium fuzz circuit to operate daisy-chained with other standard negative-ground effects (Pump'd Up Rangemaster Plus, Pump'd Up Fuzz Face, Pump'd Up Tone Bender, and the Fuzzy Bee). It can also be used in a circuit to provide both +9V and -9V to allow an 18V circuit to be created from a 9V source, which is what the original Klon® circuit does.

The 7660 (no S at the end) was problematic because it has an internal oscillator which is in the audible range, and causes guitar effects to have whine noise. The MAX1044 and 7660S solved this issue by adding an oscillator boost that eliminates this noise. Unfortunately, the MAX1044 has been less than reliable for some so we shy away from those. These 7660S charge pumps are fantastic and seem to be highly reliable. These are guaranteed authentic. Brand will vary from time to time but will be either MicroChip or TelCom (both datsheets available below).
