ISL8270/71M
Digital DC/DC PMBus 25/33 Amp Modules

Intersil’s ISL8270M and ISL8271M are 25A and 33A step-down DC/DC power supply modules 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 25/33A of continuous output current can be delivered without a need of airflow or a heatsink.

The ISL8270M/71M devices use ChargeModeâ„¢ control architecture, which responds to a transient load within a single switching cycle with a compensation free design. The ISL8270M/71M come with a preprogrammed configuration for operating in a pin strap mode, and more configuration such as soft-start, fault limits, current sharing, and external voltage tracking can be easily programmed or changed via PMBus compliant serial bus interface. The ISL8270M/71M family is supported by Intersil's PowerNavigatorâ„¢ software, a graphical user interface (GUI) that can be used to configure modules to a desired solution.
