The TK75018 is a monolithic switched capacitor converter with feedback control. With just two capacitors, the TK75018 can create a negative voltage supply which tracks a positive supply. As an alternative, the feedback pin can be used to establish regulation at a desired voltage, and it can also be used as a shutdown signal input. A single TK75018 can also be configured as a non-inverting step-up converter or dual output voltage doubler.
