Description

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 as shown in Figure 3.

The current capability of STOD2540 allows feeding a 1", 1.3" or 1.5" color PMOLED. STOD2540 is a boost converter that operates from 3.0V to 5.5V and can provide an output voltage as high as 25V. The output current capability is maximum 40mA up to 25V output voltage.

The regulation is performed by a resistor divider network ( Figure 3.) that detects the output voltage. In this state-of-the-art boost converter, a DC current path exists between the battery source and the load. In order to reduce the consumption in Shutdown mode, a high-side load isolation switch is necessary to cut this DC current path in Standby mode. The Load Disconnect Switch (LDS) actsas an isolation switch in Shutdown mode.
