STOD1812 is a synchronous 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. 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.
