ISO5852S: Regarding Switching frequency

Part Number: ISO5852S

I would like to know what will be the maximum switching frequency this driver IC permits?

  • Hi Saravanan,

    ISO5852S can theoretically support up to 1MHz switching frequency because of tight timing specs. However, the actual switching frequency would be limited by thermal. High frequency switching can generate lots of heat and push the junction temp beyond 150C. Regarding thermal analysis, you can follow the section 10.2.2.9. Please let us know of any further questions. 

    With Regards,

    Xiong
