Hello Team,

Are there any thermal measurement on the LMR33620, 2.1MHz and full 3A load? I would like to see the thermal performance under these conditions in the VQFN package.

Julio,

Are you looking for 5Vout or 3.3Vout?

Here's the thermal image for 12VIN, 5VOUT, 3AOUT, 2.1MHz, 22C still air ambient. IC case top temp = 67.4C
