Hello,

Please let us know Theta Ja and Theta Jc value for LM5069MMX-1/NOPB.

I could not find them in the datasheet.

Thanks and best regards,

Hiro

    Hi Hiro,

    Sorry for the delay. The values are as follows:

    RθJA Junction-to-ambient thermal resistance 156.0 °C/W
    RθJC(top) Junction-to-case (top) thermal resistance 50.6 °C/W
    RθJB Junction-to-board thermal resistance 75.8 °C/W
    ψJT Junction-to-top characterization parameter 4.8 °C/W
    ψJB Junction-to-board characterization parameter 74.5 °C/W
    RθJC(bot) Junction-to-case (bottom) thermal resistance N/A °C/W

    These values will be included in the next datasheet update for the LM5069.

    Thanks!
