TPS26630-33EVM: About Current Limit

Part Number: TPS26630-33EVM

Hi,

I have 10mF capacitive load. I couldn't charge the capacitors with EVM board. Please check the scope screen, it is output pin. Input is 28V. DV/DT cap is 1uF. Current limit is 3k.

  • Hi Alikaan,

    Looks like thermal shutdown is happening. We need to adjust dvdt cap. We have a design calculator on product page that can help predict startup. Can you share filled sheet for review?

    Regards
