TK75018
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
µA over the full operating
temperature and input voltage ranges.
