The ISL8270M is not recommended for new designs and has no alternative product available.

The ISL8270M is a 25A step-down DC/DC power supply module 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 25A 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 ISL8270M uses ChargeMode™ control architecture, which responds to a transient load within a single switching cycle. The ISL8270M comes with a preprogrammed configuration for operating in a pin strap mode: output voltage, switching frequency, and the device SMBus address can be programmed with external resistors. More configurations, such as soft-start and fault limits, can be easily programmed or changed using a PMBus compliant serial bus interface. PMBus can be used to monitor voltages, current, temperatures, and fault status. The ISL8270M is supported by PowerNavigator™ software, a Graphical User Interface (GUI) that can be used to configure modules to a desired solution. The ISL8270M is available in a 40 Ld compact 17mmx19mm HDA module with very low profile height of 3. 55mm, suitable for automated assembly by standard surface mount equipment. The ISL8270M is RoHS compliant by exemption.
