Hello,

We dont have an EC specification guarantee fpwm and auto mode transition. Many customers have no issue with the transition time and the product is marketed as being able to "switch on the fly."

My recommendation is for the customer to evaluate in their system to see if the performance is acceptable.

Hi Beck-san

Thank you for your reply. If you can, could you show us any waveform?

We want to know any concern about changing switching mode dynamically.

Because we use power line communication by this power, so any ripple cause unpredicted failure.

Pls give us kind corporation.
