I was told to use **broken link removed** as a DC/DC converter to make 2.7V - 3.6V (at up to 9A) into 24V-36V at 1 A. (Yes, I know that problem 1 is that the input voltage I have is too small for this chip, but pretending I can double it for now, let's get into the other issues.)
Like most LED drivers I'm seeing, there is a PWM associated with it. Can these be run at 100% duty cycle to provide constant DC output? Let's just say the device I'm powering would not be happy with fluctuating voltage (mini-CPU) so if not, that's bad.
Ideally my converter (for the Vo and Vi above) is 90% efficient or greater and fits into a cubic inch.
I laughed when I heard the requirements, but then again what do I know.
In the meantime, I'm trying to get as close as possible. Could it be that an LED driver is the answer? I have trouble believing a chip this small can do this for me with constant current output without massive heat problems at the very least...what am I missing?
Any suggestions on anything that come close to my requirements?
