Variable output, negative voltage IC
BD6111FV
Description
The BD6111FV is a charge-pump, negative supply IC
containing a regulator. The charge pump block inverts
a positive power supply voltage that is inputted to
VBAT pin into a negative voltage and outputs it from
the NEGOUT pin. The regulator block stabilizes this
negative voltage with low-noise and outputs it from
OUT pin. Output voltage values of this regulator can
be controlled by voltage value inputted to VIN pin and
determined by OUT=-1.6 VIN .
