Description

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.

With no external timing elements, the converter will self-oscillate at 25 kHz, nominal. This frequency can also be user adjusted with a small capacitor or synchronized to another oscillator.

Quiescent current is typically 2.5 mA. Standby current is guaranteed less than 200  A over the full operating
temperature and input voltage ranges.
