Abstract

This paper introduces a practical power supply design method for the display panel of smartphone. The specific goal of this design method is to reduce the voltage stress over the internal MOSFET of the power supply for more reliable operation. A power integrity analysis is conducted to evaluate a factor which increases the voltage stress over the internal MOSFET. Based on this analysis, two PCB layouts are designed for case studies. Reduced voltage stress is verified in the case study.
