With mine, I found that I got better performance with lower frequencies.
For the small transformer, it could only properly regulate at a lower
output voltage than the bigger transformer. Essentially, if the output
voltage on your converter drops when you load it, just try running it at
that low
Is your transformer (inductor) getting too warm ? It's possible that the
peak current is larger than Isat; at saturation the magnetic efficiency
drops way off.
It's not easy to measure the inductor current, because parasitics are
introduced by the scope-probe. Most often, the ground lead picks-
Thanks for suggestions. The smaller one looks like like it should do the
job with correctly designed converter - the one I found doesn't look like
it can dissipate more than 100mW without damage.
Same story for me and CJ5143 - I've received two of those as free samples.

BTW, Wurth have happily be provided me with samples for many of their products.
As a result, they have a loyal customer.

Hi Tomasz,
I used this transformer from Wurth in one version of my power supply:
http://katalog.we-online.com/pbs/datasheet/74488540250.pdf. It is 4mm high.
That version of the power supply will easily drive two tubes from a LiPo
battery. It will manage up to four IN-12.
The whole project is d
Thanks for confirmation.
I was recently researching possiblities of making an ultra small PSU with
<1W output (nixie watch project) and I'm currently stuck with CEEH54 and
CJ5143 and I'm toying around with them.
However, I've found another little gem to order and play with:

Yes you're right, same solution with NCH8200HV for power supply module,
height of transformer is 5mm max, pcb board thickness is 1mm, this's the
thickest part, check picture attached. Actually I have another choice for
make it thinner with 4mm transformer, but it seem to be nosence compared t
Thanks Terry ;)

Beautiful clock - I'm kicking myself for not thinking of the name myself!

I love how thin this clocks base is. I'm wondering how the power supply is
made - judging from dimensions of your NCH8200HV power supply, fitting that
transformer isn't an option - or am I wrong? Or is it a boost converter on
a flat inductor with voltage doublers?
Anyway, this is the thinnest cl
Yan -- fantastic work as always!
