URGENT HELP FOR SMPS DESIGN AT 1MHz SWTICHING FREQUENCY

[BHARATKUMAR]

Dear Members,

I am in urgent need to design and realize SMPS ( DC/DC Converter) with
switching frequency 1MHz. Please advice me how to go ahead with such
high switching frequency. I have only design smps with about 100 khz
switching freq. only.

Please help in my design to selecte various components like PWM
controller, mosfet, inductor design using Magnetics Toroidal cores.

Initially I will design for single output of +5 volt, 2 amp capacity
and Input is Variable DC voltage range from 25V to 44 Volt DC.

Send your suggessions, comments, applications note details, reference
or design steps details so that I can complete soon.

Thankx in advance,

Bharatkumar.

I presume you represent the Marketing dept. and are attempting to do this on
the cheap.

Screw you, like you're attempting here.

Buy a smps that operates at 1Mhz and study that.

By the way... I'm looking for one too..so let me know where I can find
one. Thanks

Yeah...that 50% 50% 50% gag* is hilarious when I get that puzzled
look.
If I get no reaction, I take it as a bad sign and the customer gets a
negative point. The customer is either humorless, not paying attention
or just plain dum..
A puzzled reaction is ok and it's a cautious reaction in case the joke
is an error.
Laughter is best and is a sign someone is on the ball with a sense of
humor too. Those are my preferred customers.

*1st heard it in the spoof movie Loaded Weapon..

It amazes me to see how many people don't get it. 1 mhz indeed just what for when it comes out as DC.
