BD6111FV

www.DataSheet4U.com 99W028A 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 . Dimension(Units:mm) Features 1) Highly efficient, built-in inverting charge pump 2) Built-in variable, negative voltage linear regulator. 3) Built-in stand-by switch circuit (pull down resistor 1M Ω) 4) Compact SSOP-B8 package SSOP-B8 Applications Compact information computer terminal, such as PDC, PHS and PDA. Battery driving apparatus requiring negative voltage.
