PCB - Charge Pump, -9V from +9V, Screw Mount
Screw mounted charge pump PCB for positive ground effects. This small PCB provides -9V when used with a standard +9V power supply. This is a great option for positive ground effects such as vintage fuzz pedals. The PCB has a low profile design and is a simple addition to any build using a standoff to mount the board.
This board is compatible with the MAX1044, TC1044S, TC7660S, and LT1054 charge pump ICs.
