Part Number: PMP4408 Tool/software: WEBENCH® Design Tools To John Fullilove
The question is, what component values are causing the failure of the Hiccup Mode and causing it to not operate when Io is greater than ~ 3A. Also, how to fix the output of the…
Hi Bruce,
Thanks for your interest in LM5023. 10W to 65W is the typical output power range we this controller used in but it is possible to go higher than 65W. An example of this is PMP4408 which is a 120W quasi-resonant flyback converter based on LM5023…
Hello Sathishkumar,
Indeed, you can use LM5023 for a 100W converter, with those specifications.
This link http://www.ti.com/tool/PMP4408 takes you to an older reference design for an off-line 120-W dual-output converter.
Obviously, it is not designed…
Hello Imtiaz,
There is quite a large difference in power level and output voltage. Your original model is designed for a 6 mW supply and you are tying to converter it to 108W supply. There is quite a large difference in power levels and most likely will…
