How to choose a MOSFET and Transformer for DC/DC converter

[praveen]

Hello,

I am new to power supply design.

I am design a power supply for SLIC. It need dual supply -72 v @50 mA
and -24 @ 200 mA.

I also wanted to know how to select MOSFET IC
(What all parameters to be considered),Transformer.

Please give me reference (application notes explaining how to select).

waiting for reply,
With regards
Praveen

I wanted to know what is maximum stress voltage on the MOSFET,what is
the current through the MOSFET?
