Conv DC-DC Single Step Down 4.5V 14V 58-Pin HAD Module T/R

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 heatsink. The ISL8272M can be placed in a current sharing configuration with up to 4 modules in parallel to deliver 200A continuous current. The ISL8272M is built in a compact (18mm x 23mm x 7.5mm) and low profile overmolded HDA package, suitable for automated assembly by standard surface mount equipment.
