ISL8270M
Digital DC/DC PMBus 25A Module
The ISL8270M is a 25A 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 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.
