LM2991QML: Thermal Resistance

Jejomar Ildefonso

Part Number: LM2991QML

Hi Team,

Requesting for our customer. Do we have information on the junction-to-board and junction-to-case thermal resistance for LM2991QML, particularly for the CFP (NAC) package variant?

Thanks in advance!

Kind Regards,

Jejomar

Hi Jejomar,

I apologize for the delayed response.

The junction to case information is listed on the DS:

Furthermore, there is a document in our Product Folder that displays some of this information:

LM2991QML SMD 5962-96505

I will have to dig deeper to find out if there is any Junction-to-Board information.

Best,

Edgar Acosta

Hello Edgar,

Many thanks for your help about the junction to case information. Can we ask for an update if you're able to find any information about its Junction-to-Board thermal resistance?

Kind Regards,

Jejomar

Hi Jejomar,

I submitted a request to obtain Thermal simulations for this device using JEDEC standards, however, this does require some time and it could be up to 2 weeks depending on the workload. I will update you once this information is provided.
