The ISL8273M is a 80A step-down DC/DC power supply module with an integrated digital PWM controller, dual-phase synchronous power switches, inductors and passives. Only input/output capacitors and minimal passives are needed to finish the design. 80A of continuous output current can be delivered without a need of airflow or heatsink. The ISL8273M uses ChargeMode™ control (ASCR) architecture, which responds to a transient load within a single switching cycle.
