ISL8270MAIRZ规格书详情
The ISL8270M is a 25A step-down DC/DC power supply module
with integrated digital PWM controller, synchronous power
switches, an inductor and passives. Only bulk input and output
capacitors are needed to finish the design. The 25A of
continuous output current can be delivered without a need of
airflow or a heatsink. The thermally enhanced HDA module is
capable of dissipating heat directly into the PCB.
The ISL8270M uses ChargeMode™ control architecture, which
responds to a transient load within a single switching cycle.
The ISL8270M comes with a preprogrammed configuration for
operating in a pin strap mode; output voltage, switching
frequency and device SMBus address can be programmed
with external resistors. More configuration such as soft-start
and fault limits can be easily programmed or changed via
PMBus compliant serial bus interface. PMBus can be used to
monitor voltages, current, temperatures and fault status. The
ISL8270M is supported by PowerNavigator™ software, a
graphical user interface (GUI) that can be used to configure
modules to a desired solution.
The ISL8270M is available in a 40-pin compact 17mmx19mm
HDA module with very low profile height of3.55mm, suitable
for automated assembly by standard surface mount
equipment. The ISL8270M is RoHS compliant by exemption.
