HI

Search TI site , probably you will find some application note or data sheet (those are very old IC)

Why not to switch to new technologies there are many new IC for power switching

All the best

I have always found that Linear Tech are the best for switching regulator chips.
expensive, but they are good.
I havent checked TI, they are also good.

have a look at the linear tech LT1952-1

http://www.linear.com/product/LT1952

check out  their design notes etc

I hope this helps

Based on what I see as your skillset, use webench: http://www.ti.com/ww/en/analog/webench/power.shtml
