average model of dc-dc converter
To amriths04,
I do not like to involve too much math here, so I just give some hints and you find out the rest yourself.
I think you already have the book "Fundamental of Power Electronics" by Robert Erickson, so you have the state-space averaging model of one...
state space model of dc dc converter
To amriths04,
IT IS A NON-LINEAR MODEL! if you took the duty ratio as a state variable. You CANNOT took the duty ratio as a constant in deriving the dynamic model of the system.

The averaging only screen out the effect of switching. The average model still be a non-linear model. Linearization is necessary to apply linear control theory.
Re: Analog Design
Read the following subjects of one analog IC book:
1. CMOS basic device model.
2. Single stage amplifier.
3. Current Mirror.
4. Op-amp.
5. Comparator.
6. Bandgap reference.
Then you can start designing some circuits and pick up the others latter.
Below is a circuit that transfer a voltage reference to VDD to a voltage reference to GND. It cover the voltage drop VDD-VSENS to VO. Please help to analyze the circuit. Thanks.
True, or more specifically, the resistor build up a voltage drop instantaneously so that the the built-in current/discharge path, usually a diode-connected MOS or PNPN works first, and hence protects the other circuits.
You had better to get a MSEE first.
After all, it only took you 2 or 3 years. And, if you can accept the salary much less than you have now, then of course you can throw away your salary completely for 2 years.
uvlo
UVLO is just a reference and a comparator that can work under very low voltage.
An issue should be concerned: if the supply voltage is too low for UVLO to work properly, the circuits that supposed to be shutdown won't be turned on occasionally.
You will meet the issue in designing the UVLO.
