For this application note, solutions were chosen optimized foran output current of 50 to 100 mA, where there was a choice.This was intended to provide some margin for programminga single device, and immediate capacity for programming atleast two devices. For all solutions, Iomax exceeds 100 mA,and most manufacturers offer migration paths for even greatercurrent requirements. All final designs include an inhibit fea-ture, that allows the system to turn the converter off whendevices are not being programmed. Surface mount compo-nents and pricing were used wherever possible, and all solu-tions were prototyped and verified.
