While not the best for the job, it's certainly appealing at .22c versus

But taps out at 3A. if there's a way to cull some wattage from the 20w point.

that's a 404 not found chris.
When will I learn to stop posting links from my Shopping Cart?
Here's the correct link. http://www.digikey.com/product-detail/en/AP6503SP-13/AP6503SP-13DITR-ND/2767...
anyway pending no complete howlers i'll probably go for the TPS56428 as it's $1.10 in 1k volumes (TDK inductor is $1 as well, eek!) - the TPS56428 looks like quite an awesome and well-designed bit of kit, no completely mad thermal thingies like the LM1084, good advice from TI in the datasheet so... yeah.
Regarding the AP6503, if possible, may be able to do dual AP6503's, and I was looking at the wrong line in the spreadsheet. It's .33c not .22c in qty of 2500. STILL not bad, and the datasheet has really good wiring instructions.
