LMG3616: Recommendation level

Part Number: LMG3616
Other Parts Discussed in Thread: LMG3626, LMG3622, LMG2610, LMG3612

Tool/software:

Hi team,

Why is the LMG3616 not listed in the GaN table? Is it a less recommended product?

The stock is always at zero, when will it be replenished?

    Hi Hirotsugu, 

    Thanks for reaching out. The LMG3616 is not a less recommended product, it is simply a variant of the more commonly used LMG3626. The difference between LMG3616 and the LMG3626 is the current sense emulation (lossless current sensing) feature. We have plans to somehow incorporate LMG361x devices into the table you showed. 

    Are you needing samples for an active project? We are working to replenish our stock at the moment.

    Thanks,

    John

    Hi John-san,

    Our customers are very concerned about whether they are using products that are in line with the manufacturer's trends.

    Are LMG3616 and LMG3622 recommended products?

    Have they already been used in power supply applications?

    Is it appropriate to use LMG3616 and LMG3622 for AC85~264Vin 5V/12A output in ACF topology?

    Hi Hirotsugu, 

    If customer is interested in our TI GaN for ACF, for 60W, we would recommend LMG2610 GaN half-bridge with integrated gate drivers, level shifter, bootstrap diode, and lossless current sensing. If they still would like to use single GaN FET devices, there is no problem with using LMG36xx, but for ACF, we heavily promote LMG2610. 

    Thanks,

    John

    Hi John-san,

    I think the combination with the LMG2610 would be better, but they chose a discrete configuration to add variety.

    I think they are also evaluating competitor GaN, but are concerned about whether their choice of TI's GaN is appropriate.

    Hi Hiorotsugu-san, 

    Okay, that is no problem. Please communicate with them that there is no concern with using LMG3612 or LMG3622 devices. We do recommend these devices to customers for these types of applications. 

    Thanks,
    John
