Estimating power dissipation for MC08XS6421

Hello everyone,

I'm currently working with the MC08XS6421 and trying to estimate its switching losses in a bulb driving application. Unfortunately, the datasheet does not provide any specific information on switching energy.

I would like to inquire if you have any additional helper tools that could assist in expediting the design phase. Specifically, I am interested in:

  • Calculation spreadsheets
  • R/C thermal models
  • Spice models

Thank you in advance for your help!

Best regards,

Ko

Hello Kostiantyn,

I have reached out to our internal team to check the availability of any dedicated tools or models that could assist with your design efforts. While the datasheet does not currently provide specific switching energy data, I am actively looking into whether calculation spreadsheets for power dissipation/thermal analysis and thermal/SPICE models are available for this device. 

I will update this thread as soon as I receive confirmation on the availability of these resources. Thank you for your patience.

BRs, Tomas
