Flyback DC/DC Controller drives external N-channel power MOSFET.
DC to DC Power Supplies (Converters)

Flyback DC/DC Controller drives external N-channel power MOSFET.

Operating over 5-100 V input range, Model LT3748 simplifies design of isolated DC/DC converters. No opto-isolator, third winding, or signal transformer is required for feedback since output voltage is sensed from primary-side flyback signal. Isolated device operates in boundary mode, which is a variable frequency current mode control switching scheme, resulting in ±5% typical regulation...
