Isolated Power Supply Diagram. For example they can be used to enclose a standard and an emergency isolated power system in a single back box with common trim. Thus this design generates four isolated power rails.
Wds provides most necessary information such as turns ratio volts us product etc. Hence a smps can be used to convert ac to dc such as in a desktop computer power supply or dc to dc either step up or step down in many different battery powered systems.

The max17686 is a high voltage high efficiency iso buck dc dc converter designed to provide isolated power up to 5w.
These isolated gate drivers require isolated power supply which is provided by this reference design. One combined power supply rail for the three bottom igbts and three isolated rails for each of the top igbts. Flyback converter circuit diagram and working. The switching frequency is around 100 khz.
