I’m working on a 3.6v lithium ion battery charger based on the LT3652. more later, I just like how it looks in CAD.

Say, that looks pretty swank! When are you gonna have it made up? Next board order? I look forward to seeing how it comes out. Nice work.

yeah, they’ll be run in the next dorkbot pcb order. I’ll have them back on the 12th of August.
I also need to put together a boost/regulator to bump that 3.7v Lithium Ion to 5V.
I did a quick search of LT for you and came up with this:
LTC3427 – 500mA, 1.25MHz Synchronous Step-Up DC/DC Converter in 2mm x 2mm DFN Package
That’s a Switching boost converter that will output 500mA. I’m assuming you won’t need more than that . However, if you do need more current we have:
LT3473 – Micropower 1A Boost Converter with Schottky and Output Disconnect.
That first package costs $2.59 in single quantities while the second runs as low as $2.79 for single quantities. Also, you can get free samples (two of any one chip) from them if you have a business name and such. That’s how I got the chip for my buck regulator that I did. It’s great for prototyping on the cheap.
Luck with that regulator!
