Eval Kit DC2134A Thermal Management

Hi EZ Team,

Eval Kit DC2134A for LTC4020EUHF uses Vishay MOSFET which mentions 1”x 1” surface mount and 2 oz of copper for Junction to Ambient thermal resistance.

However the evaluation board does not have 1”x 1” area for thermal dissipation.

Can you kindly explain the reason behind not having 1”sq area for MOSFET other than M3,M9 and M1.


Can you please provide the details how you calculated the required copper area for the MOSFETs in the Eval kit DC2134A?

Thanks & Best Regards,
