UCC28630: UCC28630 output accuracy at over temp

Part Number: UCC28630
Other Parts Discussed in Thread: UCC28600, UCC28704, UCC28740

HI

There is a reference circuit 150W AC/DC with UCC28630

http://www.ti.com/lit/ug/tidub50b/tidub50b.pdf

Is there output accuracy data for over temperature(–10°C to 55°C) ?

 

There are Load regulation and Input regulation data, but could not find over temp data.

 

best regards K.Kanao

    Kanao-san,

    Thanks for your interest here. I will check with the original design team if they have that data. Usually they do not fully characterize over temperature for TIDA.

    You are interested in Vout regulation at full load over temp? Or at some light load point?

    Regards

    John

    Kanao-san,
    I confirmed with the TIDA design engineer that did this board that they do not have data at temp. Only data at room temp which was included in the report.

    What is the key concern? Perhaps we have other data from other designs that may be able to assist you.

    regards,

    John

    Hi John
    Thank you for your reply.
    I would like to know the performance of Primary Side Regulation Flyback (UCC28630) compare with Flyback (UCC28600) using opto-coupler.
    It would be good another device of temperature data.

    best regards K.Kanao

    Kanao-san,
    we don't have full system data to compare but in general UCC28630 is considered capable of +/-3% Vout, devices like UCC28704 are considered +/-5% capably, and opto-feedback controllers like UCC28600/UCC28740 are generally capable of +/-1% Vout tolerance.
