TPS562243: Thermal Shutdown

Hi Kaushik,

Will the TPS562243 IC enter thermal shutdown under the following conditions?

Nope it should not if the layout is well taken care of.

Additionally, we would appreciate recommendations on how to minimize heat buildup and ensure reliable thermal performance.

I'm unable to see thermal reliefs into internal ground planes. Can you please confirm the same? 

Regards,

Gautam

we use solid ground plane in 2nd layer and 7th layer for 8 layers of PCB. We use through hole via for GND plane.

If you recommended to put extra GND vias. then a will do for better thermal.

Kaushik, generally Thermal relief (PTHs) are recommended close to the chip ground plane.

The IC package is SOT-563, So I will put PTH via as much as possible.

Any further suggestion would be appreciated.

Couple of them should suffice. That's all. 

Thanks Gautam.
