dead time generator circuit mosfet push pull
For starting with smps design ,my first advice would be read the books of Marty Browm ,Abraham Pressman and Chryssis .
For my first steps with smps's i builded a testboard with SG3525 (like proposed in the ST datasheet) to get a good understanding of the oscillator .
Start out of safety precautions with a low voltage ,take lets say a 24 Volt transformer and make your first trials with 24 Volt ac input .
(also always use fuses)
This keeps you safe ,and the chance your parts survive a small mistake are bigger .
On the website of texas instruments you can find the unitrode seminars and also they have webcasts about prototyping smps's .

They offer quite good learning material and reference designs .
Personaly i would say start with pushpull or halfbridge (in case of higher input voltages) ,SG3525 is good for a lot of topology's and it doesnt differ much from more or less every pwm generator .
For halfbridge IR2153 is good for a very simple setup it has oscillator ,halfbridge driver and fixed dead time all in a dil8 .
But i would suggest to start with reading your way into this matter (maybe start with one of the examples from Marty Brown can fill in your own requirements but also can check your calculations)
Then build it and measure ,understanding comes with aswell theory as practice .
Good luck and be carefull with your eyebrows .
