LM5005MH rectangle signal at pin switching node
Part Number: LM5005
Tool/software: WEBENCH® Design Tools
i'm using the LM5005MH with an input voltage of 54-60 volts. The folowing values are used:
Rt: 24kOhm / 1%
Lf: 33µH; Cramp: 330pF
Rfb1: 1,69kOhm / 1%; Rfb2: 1kOhm / 1%
Vcc: 8 volts with an external regulator
I tried to some things to get a better result with this input voltage, but i'm still not happy with the output voltage:
The current in this project is 500mA - 600mA. Does anybody have an idea what to try? Thanks for your help.
