Abstract

A new DC-DC converter was designed for gate driver circuit using low temperature poly-Si TFT technology. To achieve high efficiency and small area, we proposed a cross-coupled type DC-DC converter which converts 5V of input voltage to 9V of output voltage and supplies 120$\mu$A of current to load. Its efficiency is 92.9% and the area is reduced as much as 19% compared to the previously reported latch type DC-DC converter.
