The ISL8272M is a 50A step-down PMBus compliant digital power module. Integrated in the module is a high performance digital PWM controller, dual-phase power MOSFETs, inductors, and the passives. This high efficiency power module is capable of delivering 50A without the need for airflow and heatsinks. The ISL8272M can be placed in a current sharing configuration with up to four modules in parallel to deliver 200A continuous current.
