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.
1) Built-in high efficiency, inverting charge-pump
2) Built-in negative voltage regulator
3) Built-in standby SW (pull down resistance 1MΩ)
4) Ultra small MSOP8 package
Small terminal devics such as cellular phones, PHS, and PDA etc.
Other equipments driven by battery required for negative voltage.
