LMG2610: Max power & Fsw able to handle

Kei Kuwahara
Expert 5740 points
Part Number: LMG2610

Hello team,

What is the maximum power LMG2610 can achieve in Flyback or Forward converter (active clamp)?

I saw in UCC28782EVM-030, LMG2610 can handle 65W, but I want at least 150W.

Also, what is the max switching frequency LMG2610 can handle? On UCC28782EVM-030, I could onyl find up to 500kHz characteristic.

Best Regards,
Kei Kuwahara

    Hello Kei,

    Max power level is not easy to define hard limits, it will greatly depend on the main RMS currents, device losses, and thermal solution used. Some topologies can achieve higher power levels with lower RMS currents, such as asymmetric half bridge (AHB) or LLC.
    For a typical active clamp flyback (AHB), the device losses and thermals will most likely reach a maximum at 75W. This is why the datasheet mentions < 75-W applications. However, when used in other topologies such as AHB, this can potentially be much higher.
    I have more information about this topic that I can share with you through email, I will reach out later this week.

    For maximum switching frequency, I need to verify with our team, I will also include this information in out email thread.

    Thanks,

    Zach Soviero

    Hi Zach-san,

    Thank you for the explanation. I will wait for your email.

    Let me know if discrete GANFET (no gate driver) is more suitable for higher power application.

    Hello Kuwahara-san,

    I sent you an email to address your previous switching frequency question and high power applications.
