Part Number: TPS768

I would like to request for the following information for TPS76801QD:

1. Junction-to-Board thermal resistance (Theta_JB) information

2. Junction-to-Case (Top) thermal resistance (Theta_JC (Top))

Thank you!

Hi Benedict,

I have reached out our Thermal Group. Please allow up to 1 week to obtain results. These will be based on JEDEC standards. I will follow up as soon as the results are done.

Best,

Edgar Acosta
