TPS56C215: Thermal shutdown

Part Number: TPS56C215

Hi

When the load is 10A, this chip will always protect itself due to overheating. Is there a recommended way to dissipate heat?

Input/Output Voltage >> IN: 12V OUT: 3V/10A

IC and inductor temperature >> about 80 degrees

    Hi Gareth,

    I don't think OTP would be triggered under 80℃.

    And it seems the layout is ok.

    Are you sure the device shutdown due to thermal? Is there a hiccup performance?

    Could you please show me some waveforms of the case?

    Thank you!
