In this this paper, an IP driver block was designed and simulation conducted for an AMOLED display which supplies power as selected by users. The IP driver design focused on the regulation of output power, due to the OLED characteristic for diode electric current according to voltage, to be activate by Pulse-Skipping Mode (PSM) under low loads, and 1.5MHz PWM for medium/high loads. The IP driver was designed to eliminate ringing effects appearing from the Dis-Continue Mode (DCM) of the step-up converter.
