Demonstration circuit 3006A is a compact no-opto isolated flyback converter featuring the LT3001. The DC3006A outputs 12V, and maintains tight regulation with as load current from 1.5mA up to 300mA over an input voltage from 4V to 32V. The output current capability increases with the input voltage, as shown in the Performance Summary table.
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 voltage rating of 65V with an RC snubber and a TVS clamp which damp the ringing and clamp the MOSFET drain voltage to a safe level.
The Performance Summary table summarizes the performance of the demo board at room temperature. The demo circuit can be easily modified for different applications with some pre-designed transformers.
The LT3001 datasheet gives a complete description of the part, operation and application information. The datasheet must be read in conjunction with this quick start guide for demo circuit 3006A.
