DI-168 and DI-130 questions

Posted by: thomasliew on

DI-168:
Where can I obtain additional information on the PFC as well as a detailed eplaination of the whole circuit?

DI-130:
Where can I obtain additional information on the active current sense circuit?

Thanks.

The Engineering reports associated with Dl-168 and Dl-130 have fiarly complete circuit descriptions. If you have a specific question(s) about operation of either circuit design I may be able to help.

I found the engineering report associated with DI-168 but not for DI-130. Could you advise the engineering report associated with DI-130? For DI-130, how good is the valley fill circuit. It seems that the PF can be corrected to 0.7~0.9. What would be the typical PF correction achievable? For DI-168, I am interested in the power factor correction. However, very little is mentioned about how power factor is done and how to tune the circuit for good PF correction. Thanks.
