I'm not really making an LED driver. It's a battery charger but they're essentially the same problem. I need a voltage limit and a current limit. You could also say I need a current source with a precise voltage limit.
The HiperTFS has two supplies, a two-switch forward and a standby flyback. I only want a forward converter. Do I have to include a flyback stage? In all the schematics, the flyback stage has the bias winding. If I put the bias winding on the forward transformer, will the supply be able to start up?
