Renesas Electronics Corporation Digital DC/DC PMBus 33A Module ISL8278MAIRZ

Description
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 need for airflow or a heatsink. The thermally enhanced HDA module is capable of dissipating heat directly into the PCB. The ISL8278M uses ChargeMode™ control architecture, which responds to a transient load within a single switching cycle. The ISL8278M comes with a preprogrammed configuration for operating in a pin-strap mode. Output voltage, switching frequency, and 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 ISL8278M is supported by PowerNavigator™ software, a Graphical User Interface (GUI) that can be used to configure modules for a desired solution. The ISL8278M is available in a 41 Ld compact 17mmx19mm HDA module with a very low profile height of 3.6mm, suitable for automated assembly by standard surface mount equipment. The ISL8278M is RoHS compliant by exemption.
