We are planning to use LM2673 in one of our new designs. Request you to clarify the following
1) Shall I use LM2673 for new design?
2) To get 5V and 3.3V from 12V which of the following option is technically better
a) 12V to 5V with one LM2673 and then 12V to 3.3 V another LM2673
b) 12V to 5V with one LM2673 and from generated 5V to 3.3V using any other part
3) Will LM2673 meets the type test requirement given in attached document.
4) Is there any better part which suits my requirement.?
