Conv DC-DC Single Step Down 4.5V 14V 40-Pin HDA Module T/R

The ISL8271M is a 33A 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 33A of continuous output current can be delivered without a need of airflow or a heatsink. The thermally enhanced HDA module is capable of dissipating heat directly into the PCB. The ISL8271M is available in a 40-pin compact 17mm x 19mm HDA module with very low profile height of 3.55mm, suitable for automated assembly by standard surface mount equipment. The ISL8271M is RoHS compliant by exemption.
