I want to make the driver but does not use IC. Can just using 13005, toroidal transformer, MOSPEC or other Schottky or ultrafast rectifier, and optical feedback for over voltage (Open Load) and over current (Shorted/Reduced load voltage). The toroidal core transformer I prefer as air gap adjustment is absent.

Simplest & Rugged circuit will be better. Passive PF improve with 2 Capaciter & 3 Diode may be added.

RomanBlack like circuit may be better but they have no Isolation & Power/Voltage Rating like my Spec.

Design idea also welcome.
