Summary:An efficient, cost effective power driver for OLED panels is configured with a small BOM without compromising the display quality. The power driver adopts only one Inverting Buck-Boost Converter (IBBC) to regulate the necessary output voltage for the OLED panel load. The output voltage to drive the OLED panel load is supplied by the IBBC and the positive input of the OLED panel is tied into the input power supply of VIN directly without any switch. A DC-DC converter is provided to generate a reference ground and drive the associated control circuits. The input DC voltage VIN is utilized as a reference voltage for both the IBBC and the DC-DC converter.
