ISL8278M Digital DC/DC PMBus 33A Module

ISL8278M Digital DC/DC PMBus 33A Module 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 the 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 architec.

ISL8278M Features

* Complete digital switch-mode power supply - Wide VIN range: 4.5V to 14V - Programmable VOUT range: 0.6V to 5V

* PMBus compliant I2C communication interface - Programmable VOUT, margining, UV/OV, IOUT limit, soft-start/stop, sequencing, and external synchronization - Monitor: VIN, V
