Part Number: UCC28070

Hi Team:

 Customer usually use UCC28070 for ①  waveform use case.

For some use cases confirmation. The rectified film capacitor output voltage is shown with ② .

Here is the target:

1.Can the chip boost normally at around 200Hz?

2. Only need the boost function. the PF better to ≥0.85 is okay.

    Hi Allen,

    I am assuming you are referring to the line frequency, in which case yes. The UCC28070 is designed to support a line frequency up to 200Hz. Here is another E2E post on the same. 

    I hope this answers your question.
