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%
Cbst: 22nF
Css: 10nF
Vcc: 8 volts with an external regulator
Df: STPS5H100B
I tried to some things to get a better result with this input voltage, but i'm still not happy with the output voltage:
- i tried Lf :100µH / Cramp: 1nF
- Rt: 11 kOhm, 20 kOhm
The current in this project is 500mA - 600mA. Does anybody have an idea what to try? Thanks for your help.
