Cool, I'm looking to use the chip for exactly the same reason, but for a power amp PSU.

I have used the same circuit for several power amp smps's already. just used bigger fets, transformers and rectifiers. the basic controller circuit is the same. I have a few varieties of open loop smps controllers here. just let me know if you want one.

Ta. Just having a problem at the moment finding a company to make me suitable transformers, as I'm running off mains so can't really wind them myself.

anyone know a cheaper source for ferrite toroids? the 10pcs of cores cost us $30 just for shipping.

You'll have to buy from a closer distributor if you want to reduce shipping charges. Buying in larger quantities would reduce the shipping/core price.

my partner is working at it at the moment. he's looking at asian sources to cut cost. not sure if there are fake ferrites out there?

from what he told me, Amidon increases the shipping charge with bigger orders so there is little to be saved. last resort would be to get a relative of his in the US to buy it so shipping will be lower but would take a while.

Have you tried cwsbytemark or any of the distributors listed on the manufacturers (mag-inc.com, etc.) sites?

I had a look at their site. didn't see suitable toroids (too big) but there are some pot cores that might work.

I'll ask my partner to check out their shipping prices. thanks
