Other Parts Discussed in Thread: TIDM-1007, LMG3410R070, LMG3410R150, LMG3410R050

Hello

Im looking to implement a heating control system, whose input will be 115V AC 400Hz. Instead of regular diode based bridge rectifier I would like to implement it with GaN FETs.Later the heating system will be controlled using PWM.

Please suggest !

Thanks

Bhargav

    Hello Bhargav,

    Yes, GaN could be a great candidate to improve efficiency and make the design more compact. There are a number of great reference designs here you can find here: http://www.ti.com/power-management/gallium-nitride/reference-designs.html#search?famid=3321. One of the example is TIDM-1007 which uses C2000 as the controller for the totem pole PFC. It's interleaved to achieve higher power and the efficiency is over 98%. 

    Based on the power level and the switching frequency, we have a family of device: LMG3410R050, LMG3410R070 and LMG3410R150 which have different Rdson and Coss.

    Please let us know if you need more specific information or have any questions.

    Regards,

    Yichi Zhang Thank you for the response.

    Is there any way I could get these modules for evaluation ? looks like these modules are not for sale and do they support mil spec?

    Regards

    Hello Bhargav,

    The documentation for TI reference design are available on ti.com, however they are not available for sale. The TIDM-1007 is designed for commercial applications. You are welcomed to go through the user guides as they contain schematics and testing results etc.

    As for the mil spec, many A&D customers have evaluated the TIDM-1007. Also what mil specs are you looking for in particular?

    Regards,
