BD6112FVM

www.DataSheet4U.com 00W148A Programmable negative supply IC BD6112FVM Description 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.
