ISL8272MAIRZ-T

电源管理 (PMIC) Stand alone digital 50A DC/DC step down

50A Digital DC/DC PMBus Power Module

The ISL8272MAIRZ-T 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.
