CHARGE PUMP BI-POLAR OUTPUT RTS PCB

A ready-to-solder PCB for the GGG bipolar charge pump. It makes +9V, -9V and ground from a single 9V supply, so you can power circuits that need a bipolar supply without a second battery or adapter.

About this PCB

The charge pump circuits come from the GEOFEX site. This board is the bipolar version: from one 9V source it gives you +9V, -9V and ground. That's handy for Craig Anderton projects and other circuits that call for bipolar power. The project page also shows how to use a charge pump to run positive-ground (PNP) circuits from a negative-ground supply, so a PNP pedal can share a daisy-chained pedalboard supply. It includes example instructions for a Fuzz Face™, a Rangemaster™ replica and two Tone Bender™ replicas.

A complete Bipolar Charge Pump kit and a separate Voltage Up (17, 25 or 33V) charge pump PCB are also sold in the store.
