Tool/software:

Hi. Can you please tell me... can the UCC3808A-1 chip be used in a push-pull topology to obtain a multi-channel voltage source with a power of up to 500 W in 24V, 12V, 5V from a 400 V voltage source??? Thanks for the answer.

    Hi,

    In theory, yes. But practically it is better to consider a full-bridge as 500W would require external driver as the device on chip driver not enough, and the 400V would require 1000V or even 1200V MOSFETS to work for 400V input.

    I suggest to use a full bridge to make 400V to 24V then add two buck to get 12V and 5V from 24V. You can consider UCC28251 or UCC28951.
