Abstract
A previous adapter have a single-ouput, however, a demand of a multi-output adapter increase in the recent industrial site. In order to satisfy the demand, in this research, we implement a programmable high efficiency multi-output adapter. The basic structure of the adapter introduced in this paper is a sort of flyback. The way for producing the reference voltage of the adapter proposed is similar to the way in the general flyback implemented with TL431. In addition to the basic concept of the design, however, we introduce a digital variable resistor, AD5246BKSZ10-RL7 and a microcontroller for changing a programmable multi-output. It makes output be variable that the digital variable resistor change the reference voltage of the adapter by order of the microcontroller. The adapter output voltage is controllable in the range of 20V by the user, and the power efficiency is proven to be 85%.
