Intersil – ISL8272M: Industry’s First Fully Encapsulated 50A Digital Power Module

intersil_June2015_pg17intersil-logo
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’s digital control technology provides precise sequencing and system monitoring through the PMBus interface. The innovative ChargeMode™ control architecture enables compensation-free design that keeps the device stable regardless of output capacitor changes due to temperature, variation or aging.
