ISL8278M Overview
ISL8278M Digital DC/DC PMBus 33A Module The ISL8278M is a 33A 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 33A of continuous output current can be delivered without the need for airflow or a heatsink.
