I have a customer who two technical queries on the :
Part: LYT7503 / 04
1. Can he run these parts on pure DC (140Vdc) ?
Application: they going to use this part in an Emergency Backup Light Application, so a switcher over from mains to DC -> will it work without being damaged?
2. Can he use the feedback pin in such a way what he wishes to use it to implement On/Off control without negative effects to the chip?
ie Can he switch it off completely using the FB pin?
