Other Parts Discussed in Thread: TL5001
Hello,
Old thread has been closed. I beg your pardon, but I have bought some new mosfets to replace IRF540N by IRFB4332 and UPS has lost my parcel !
With these new mosfets (that support 250V, 540N only support 100V), result is worse that with IRF540N.
I have done a small video hilbert.systella.fr/.../2021-05-18-144931.webm
Channel 1 (bottom) is main output (value on multimeter). Expected value is 412Vdc.
Channel 2 (top) is feedback signal (TL5001A pin 4).
You can see that TL5001A continuously starts and stops and feedback signal is not equal to 1V. This signal varies between 0.75 and 2V.
I can repost here actual design if required, but some information are available on old thread : https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/991873/tl5001a-tl5001a-compensation-network/3666902
