This package allows power system designers to effectively direct heat away from the PCB in high-current DC/DC applications. TI’s DualCool NexFET power MOSFETs allow the heat generated by power conversion to be removed from the top side through convection cooling resulting in improved power density, higher current capability and improved system reliability.
