STOD2540  
PMOLED display power supply  
Feature summary  
Inductor switcher boost controller.  
PFM mode control.  
High efficiency over wide range of load (1mA to  
40mA).  
Integrated Load disconnect switch.  
Over voltage protection with automatic restart  
Soft start with adjustable peak current limit  
Enable pin  
QFN8 (3mm x 3mm)  
Low shutdown current.  
Small external inductor.  
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.  
Supply voltage from 3.0V to 5.5V  
Application  
PMOLED display driver  
Description  
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.  
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.
