STEVAL-CLP001V1: 25V @ 40mA, 3 ~ 5.5V in

Summary

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 3.0 V to 5.5 V and can provide an output voltage as high as 25 V.

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 40 mA with an output voltage up to 25 V, while the supply voltage is from 3.0 V to 5.5 V.
