DC776A - LTC3705EGN/LTC3706EGN Demo Board | Forward Converter with Secondary Side Control, 36V ≤ VIN ≤72V, Vout = 1.5V @ 45A

Demonstration circuit 776 is a 36V-72Vin, 2-switch forward converter with synchronous secondary-side control featuring the LTC3705 and LTC3706. This circuit was designed specifically to attain a high stepdown ratio power supply in one stage in order to efficiently power 1.5V loads from a typical telecom input voltage range. Isolation voltage is 1500VDC. This circuit features secondary-side control of the supply without the need of an optocoupler.
