Design a SEPIC 12V regulator -help needed for choose the product

Other Parts Discussed in Thread: LM3421, LM3478, LM3488, LM5001, LM5022, MC33063A, TPS61175, TPS55340, TPS62163

Hello

First i'm new on power managent, so please excuse if my questions seems a little bit dump.

I have an input from 6V to 17V and need 12V Regulator. Current should be less than 1A (between 500mah ans about 900mah so 1A should be enough but maybe 2A is better for enough reserve? (but i think 1A is more efficency?)

My furhter requirements

1) Most important is to make a desing with not much noise and also a stable voltage output , because i have quite a lot of senitive sensors (magnetometer, etc)  -> so i need good EMI design/shield. Also i'm not sure but somebody told me a high switching frequency has to be choosed??? Also is the choose of the product also important or mostly only the design (with filters of course)?

2) if possible a smaller and simpler design is welcome

3) price is not very important

 

So a parametric search and webbench search i got the following products:

LM-Series:

LM3421

LM3430

LM3478

LM3488

LM5001

LM5022

or

an MC33063a

and finally the TPS61175

 

Anybody suggest which product to choose? or which 2-3 Products are most appropriate for my requirements?

 

Thank's a lot for help

Andy
