Description
The M62230FP is a semiconductor circuit for LCD matrix regulator, which will generate the divided-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 V_REF 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 V_REF.
Application
To drive LCD.
Recommend Operating Conditions (Ta = 25°C)
Supply voltage range: GND − V_CC: (if V1 > −1 V, it is necessary to support V_IN)…. −30 to −10 V
Recommend input voltage GND − V_REF: V_REF ≥ V_CC…………………………………....... −30 to −6 V
(To set V_CC, V_REF, in order that both |0 − V2| & |V_CC − V5| are larger than 1 V)
