Overview
ISL8271M Digital DC/DC PMBus 33A Module The ISL8271M 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.
The thermally enhanced HDA module is capable of dissipating heat directly into the PCB.
The ISL8271M uses ChargeModeā„¢ control architecture, which responds to a transient load within a single switching cycle.
The ISL8271M comes with a preprogrammed configuration for operating in a pin-strap mode: the output voltage, switching frequency, and the device SMBus address can be programmed with external resistors.
Other configuration options, such as soft-start and fault limits can be programmed or changed using the PMBus compliant serial bus interface.
PMBus can be used to monitor voltages, current, temperatures, and fault status.
