ISL8273M FN8704
Rev.4.00
Nov 9, 2017 80A Single Channel Digital PMBus Step-Down Power Module
The ISL8273M is a complete PMBus enabled DC/DC single
channel step-down advance power supply capable of delivering
up to 80A of current and optimized for high power density
applications. For higher output current, up to four ISL8273Ms
can be paralleled to supply up to 320A in a multiphase current
sharing configuration.
Operating over an input voltage range of 4.5V to 14V, the
ISL8273M offers adjustable output voltages down to 0.6V and
achieves up to 93% conversion efficiencies. A unique
ChargeModeв„ў control architecture provides a single clock cycle
response to an output load step and can support switching
frequencies up to 1MHz. The power module integrates all power
and most passive components and requires only a few external
components to operate. A set of optional external resistors allows
the user to easily configure the device for standard operation. For
advanced configurations, a standard PMBus interface addresses
sequencing and fault management, as well as real-time full
telemetry and point-of-load monitoring. Additionally, on-board
nonvolatile memory can store the desired custom configuration …
