DTMOS를 이용한 LED Back Light Unit용 고효율 Boost Converter 설계

In this study, the Boost Converter for BLU(Back Light Unit) is presented. In order to develop the Boost Converter with high efficiency, the input stage is designed with synchronous type step up DC-DC converter. The Boost Converter, based on the PWM control circuit, and LDO, has output voltage of +12V. The Boost Converter is designed with a 0.13㎛ CMOS process.
