Overview

DataSheet.
in LT3748 100V Isolated Flyback Controller Features n n n n Description The LT®3748 is a switching regulator controller specifically designed for the isolated flyback topology and capable of high power.
It 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.
Operating frequency is set by load current and transformer magnetizing inductance.
The gate drive of the LT3748 combined ...
