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 promising load regulation. Operating frequency is set by load current and transformer magnetizing inductance. The gate drive of the LT3748...
