12 volt switching power supply using LT3748

Using the LT3748 switching regulator controller specifically designed for the isolated flyback topology can be designed a very simple high efficiency 12 volt power supply project .
LT3748 drives a low side external N-channel power MOSFET from an internally regulated 7V supply. No third winding or opto-isolator is required for regulation as the part senses the isolated output voltage directly from the primary-side flyback waveform.
The LT3748 utilizes boundary mode to provide a small magnetic solution without compromising load regulation.
