  • Abstract
    A single-chip dual-output step-up DC-DC converter is implemented for active-matrix OLED mobile display panels. The bipolar outputs are regulated independently and integrated with a boost and a charge-pump topology sharing a single inductor. The chip is 4.1mm2 fabricated in a 0.5 mum power BiCMOS process and operates at 1MHz with a maximum efficiency of 82.3% at an output power of 330mW.
