Beschreibung
- DC2821A, Demonstration Circuit is a compact no-opto isolated flyback converter featuring the LT8302. The DC2821A outputs 12V, and maintains ±1% (typ) regulation with a load current from 5mA up to 1.4A and over an input voltage from 4V to 28V. 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. To limit this leakage inductance spike within the MOSFET voltage rating of 65V, an RC snubber and a TVS clamp are installed to damp the ringing and clamp the MOSFET drain voltage to a safe level
