Mitsubishi M62230FP Datasheet
DESCRIPTION
PIN CONFIGURATION (TOP VIEW)
The M62230FP is a semiconductor circuit for LCD matrix regulator,
which will generate the diveded-voltage to drive LCD matrix.
By changing the connection of R pin(i.e.,Change the internal
resistor ratio), M62230FP can support divided voltage ratio ranging
from 1/5 bias to 1/13 bias.
The high stability and any desired voltage levels is possible, since
the variable voltage regulator for Vref is built-in.
FEATURES
•Adjustable type voltage divider.
(The setting range of internal resistor is from 1/5 bias to 1/13
bias)
•5 resident buffer-Amp. (5 divided output)
•Low power dissipation(1.8 mA Typ.)
•Resident voltage-variable regulator for Vref.

APPLICATION
To drive LCD.
RECOMMEND OPERATING CONDITIONS (Ta=25°C)
Supply voltage range : GND-Vcc :(if V 1 > -1V, it is necessary to
support V IN)........ -30 to -10V
Recommend input voltage GND-VREF :VREF ≥ Vcc........ -30 to -6V
(To set Vcc, VREF, in order that both I 0-V2 I & I VCC-V5 I
are larger than 1V)
