Dear Sir

Good days,

 

May we check LM5118 Four Switch Conversion application, may we remove LM5113 date driver for cost saving?

    Hi

    You can remove LM5113. But, in any cases, you need gate drivers.

    Regards,

    Hi

    TPS2813 is a dual low-side NMOS driver which cannot be used for half bridge structure. You need  a half-bridge driver like as LM5113.

    Regards,

    I have a question about the LM5113 (alternative parts capable of much higher frequency), but can't post details publicly. How can I get old fashioned phone support?  This e2e thing made me choose other manufacturers in the past. I'm surprised TI still shields itself from customers. Look at Linear - best support in the industry.

    Typically you would contact your local FAE for direct support. Alternately, you can contact me directly at j-tucker(at)ti.com. I can forward your inquiry as I do not directly support any LMxxxx devices.
