Hello!
Serious good that you looked for in onsemiconductor and you chose some of the solutions that have in the site, they even have a software to calculate the PS and TR free, they are also available several books on the very interesting topic.
I recommend it to you.

almost all these sites devoted to Application engineers and Sysytem designers, but not to IC, chip designers.
So, are there any sites about IC design of dc2dc?

Re: Dc-Dc converter

I recommend TPS61040 from TI.
Lighting and Display Solutions - White LED Driver - TPS61040 - TI.com
It's easy to use on small project. It also show the negative supply circuit.
