Rev.5.00
Nov 8, 2017 50A Digital DC/DC PMBus Power Module
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.
The ISL8272M operates with the ChargeModeв„ў control
architecture, which responds to a transient load within a single
switching cycle. The ISL8272M 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 ISL8272M is supported by the PowerNavigatorв„ў
software, a graphical user interface (GUI) that can be used to …
