This demonstration board is based on the STOD2540 and 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 STOD2540 is a boost converter that operates from 3.0V to 5.5V and can provide an output voltage as high as 25V. The current capability of the STOD2540 allows the supply of a 1", 1.3" or 1.5" color PMOLED. The maximum output current capability is 40mA with an output voltage up to 25V, while the supply voltage is from 3.0V to 5.5V.
