Description  
Soft-start to limit inrush current  
UVLO protection  
STOD1812 is a step-up converter designed to  
power passive matrix OLED (PMOLED) displays,  
providing the pre-charge and biasing voltage of  
the column matrix driver. STOD1812 uses a  
pulsed frequency modulation (PFM) control mode  
technique. The high switching frequency makes it  
possible to reduce the value and size of the  
external components. This device is particularly  
suitable for battery-operated applications, where  
overall system efficiency is the major concern.  
Adjustable output voltage up to 20 V  
Low quiescent current: < 1 µA in shutdown  
mode  
Over-temperature protection  
Package: DFN10L 3x3 mm, 0.8 mm  
Operating junction temperature range:  
-40 °C to 125 °C  
Synchronous rectification has been integrated in  
the device in order to eliminate the external  
Schottky diode. An internal compensation net is  
also integrated, enabling the STOD1812 to  
provide excellent load transient performance in  
addition to good load regulation.  
Applications  
Passive matrix OLED power supplies  
Mobile phones  
PDAs  
The output voltage is set using two external  
resistors. Over-temperature protection and under-  
voltage lockout (UVLO) functions are integrated in  
the device. An additional switch implements a true  
load disconnection feature which stops the  
Camcorders  
Digital still cameras  
currrent flowing from the input when the device is  
in shutdown mode. The EN pin turns off the  
device, reducing the quiescent current to 0.1 µA.
