CSD163CEVM-591: 1.2V @ 25A, 8 ~ 14V in

CSD163CEVM-591 is designed to use a regulated 12V (8V – 14V) bus voltage to provide a regulated 1.2-V output at up to 25A of load current. CSD163CEVM-591 is designed to demonstrate the TPS40304 controller and TI DualCool™ NexFETs™ in a typical 12-V bus to low-voltage application while providing a number of non-invasive test points to evaluate the performance of the system.

In addition, a heatsink and thermal interface pad are provided to take advantage of the topside cooling capability of the DualCool packaging. By installing the provided heatsink and adding 100-200lfm airflow, the system is capable of delivering 25A continuous. Without this heatsink, evaluation module is only capable of 20A. See the performance curves in Section 6 of this document

Note, the topside thermal tab of the DualCool™ devices are electrically live and connected to the MOSFET source pin. As such, a thermal interface pad with electrical isolation must be used before mounting a metal heatsink. See Section 5.1.6 for further details on thermal interface pad requirements.
