Description
This demonstration board based on STOD2540 is
dedicated to passive matrix OLED (PMOLED)
displays for portable handsets and provides the
pre-charge and biasing voltage of the column
matrix driver.
The current capability of STOD2540 allows
feeding a 1", 1.3" or 1.5" color PMOLED.
STOD2540 is a boost converter that operates
from 3.0 V to 5.5 V and can provide an output
voltage as high as 25 V.
The output current capability is maximum 40 mA
up to 25 V output voltage while the supply voltage
from 3.0 V to 5.5 V
