Hi,
The attached is a 16W, 24V isolated Flyback. 100-265VAC
Uses TOP264.
Bpk is 292mT
Core loss is 0.163W
Fsw = 132kHz
There are no electrical overstresses.
Why will the chip maker refuse to support it? Refuses to supply us with samples, and says we must just give them the spec and let them do it all for us. They say its a poor design,
We are constrained in having to use the EFD15/8/5 core set due to lack of room.
The peak primary current is 1.2A. Peak secondary current is 4.97A.
I checked the core loss's for 3F3 and they are not bad. It uses the AL=63 core set.
The turns ratio is 58/14 = Np/Ns.
It is as attached. Surely there is nothing electrically or magnetically stressful about this?
There is blown air blowing all over this flyback ,and the enclosure has vent holes to the outside air.
