Hi,
I have a need to design a buck converter that can step down from 400 Vdc to variable output from 40 to 300 Vdc. The source supply is 1KW, so the current can be up to 2.5 A. The control voltage is preferably a serial digital, but a variable dc input from 0-5 Vdc will work. Is there a reference design with TI chip that I can learn from? Thank you,
Bobby.
