Intersil ISL8272MAIRZ-T

非隔离 PoL 模块，数字4.5V14V0.6 ~ 5V50A

Overview

The ISL8272MAIRZ 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 ISL8272MAIRZ can be placed in a current sharing configuration with up to four modules in parallel to deliver 200A continuous current.The ISL8272MAIRZ operates with the ChargeMode™ control architecture, which responds to a transient load within a single switching cycle. The ISL8272MAIRZ comes with operating in a pin strap mode; output voltage, switching frequency device, SMBus address, input UVLO, soft-start/stop and current sharing can be programmed through external resistors. More configuration such as fault limits, fault response, margining, and sequencing can be easily programmed using the PMBus interface. PMBus can be used to monitor voltages, currents, temperatures, and fault status. The ISL8272MAIRZ is supported by the PowerNavigator™ software, a graphical user interface (GUI) that can be used to configure modules to a desired solution.The ISL8272MAIRZ is built in a compact (18mmx23mmx7.5mm) and low profile overmolded HDA package, suitable for automated assembly by standard surface mount equipment.
