Programmable negative supply IC
BD6112FVM
Description Dimension (Units : mm)
Features
Applications
BD6112FVM is a charge-pump negative supply IC
with a built-in regulator. The charge-pump block
inverts the positive supply voltage in the VBAT pin
into a negative voltage, which generates from the
NEGOUT pin. The regulator block stabilizes
this negative voltage with low-noise that produces
from the OUT pin. Output voltage values of this
regulator can be controlled by voltage value inputted
to the VIN pin and determined by OUT=—1.6 x VIN.
00W148A
1) Built-in high efficiency, inverting charge-pump
