Analog Devices Inc. DC3006A Demonstration Circuit for the LT3001

Analog Devices Inc. DC3006A Demonstration Circuit is a compact no-opto isolated flyback converter featuring the LT3001. The DC3006A outputs 12V and maintains tight regulation with a load current from 1.5mA to 300mA over a 4V to 32V input voltage range. The output current capability increases with the input voltage. Transformer leakage inductance causes a voltage spike on the primary side after the power switch turns off. The leakage inductance spike is limited within the MOSFET’s 65V voltage rating with an RC snubber and a TVS clamp, which dampens the ringing and clamps the MOSFET drain voltage to a safe level.
