Part Number:UCC28070
Hi all
Would you mind if we ask UCC28070?
<Question1>
Does UCC28070 allow to input DC-input?
There is the description on the datesheet P4 as follows;
VINAC : Scaled AC Line Input Voltage～
<Question2>
In relation to <Question1>, if it is possible to use DC-input, does it have any caution for DC-input?
<Question3>
About Qvff architecture, does Zero-cross(VINAX<0.7V) require to operate UCC28070 normally?
And does it require every cycle?
As the background of these questions, our customer would like to use UCC28070 as Interleaved Boost Converter with DC-input.
We assume that it is better to use LM5032 instead of UCC28070.
If you have some advice, please let us know.
Kind regards,
Hirotaka Matsumoto
