Overview
MITSUBISHI (Dig.
/Ana.
INTERFACE) M62230FP LCD MATRIX REGULATOR DESCRIPTION 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.
