DATASHEET ISL8277M Digital DC/DC PMBus 25A Module FN8923 Rev.1.01 Mar 27, 2020 The ISL8277M is a 25A step-down DC/DC power supply module with an 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 ISL8277M uses ChargeMode™ control architecture, which responds to a transient load within a single switching cycle. The ISL8277M comes with a preprogrammed configuration for operating in a pin-strap mode.
