This reference design is capable of delivering up to a current of 160A with the enclosed heatsink attached at an ambient temperature of 60ºC with 400LFM or an ambient temperature of 45ºC with 200LFM of airflow.
The figures and table in pages 5 – 8 are provided as a reference design to enable engineers to very quickly and easily design a 4-phase converter. Refer to the data sheet for the controller (ISL6558) in order to optimize this design to your specific requirements. A variety of other controllers may also be used, but the design will require layout and control circuit modifications.
