DI-124, LNK304PN, Ultra wide Input Range (57 580 VAC) Flyback Power Supply

DI-124, Reference Design for LNK304PN, Ultrawide Input Range (57 to 580VAC) Flyback Power Supply. The AC input is rectified and filtered and the resultant DC applied to one end of the transformer primary winding. The 450V input capacitors are stacked with parallel balancing resistors to meet the required voltage rating
