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 .
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
Compact information computer terminal, such as PDC, PHS and PDA.
Battery driving apparatus requiring negative voltage.
*Derating:3.0mW/˚C for operation above Ta=25˚C.
