Lytswitch 4313E Driver Design
I am working on a 14W, 8-14V, 1A dimmable constant current driver. I have been using DER350 as a reference for the most part. I am trying to figure out what voltage zener diode to use for the overvoltage protection circuit. In DER 350 they use a 33v zener diode, while the output voltage is 36v. The output voltage is sensed via the bias winding which is set to 25v nominally. If I am understanding this correctly the output voltage for the secondary would then be limited to about 47v to protect the output capacitors? Is that a correct assumption?
