Texas Instruments sn6505b

Description

This application note gives out information on how to make a compact-design for a combination of signal and power isolation. There are several important points to achieve a proper design for isolation power supply that will be discussed in this app note. The board contains three independent lanes that show transformer and component selection for different requirements.
