The ISL8272MEVAL1Z evaluation board is a 4.7in x 4.8in 6-layer FR4 board with 2oz. copper in all layers. This evaluation board is designed to evaluate the ISL8272M step-down DC/DC power module. It comes with placeholders for pin-strap resistor population to adjust output voltage, switching frequency, soft-start/stop timing and input UVLO threshold, ASCR gain and residual parameters, and device PMBus™ address. More configurations, such as sequencing, Digital-DC™ (DDC) bus configuration and fault limits can be easily programmed or changed via the PMBus compliant serial bus interface.

The ISL8272MEVAL2Z evaluation board has three ISL8272M modules connected in a current sharing configuration to deliver 150A of continuous output current. This evaluation board comes with placeholders for pin-strap resistors to adjust output voltage, soft-start timing, input UVLO threshold, control loop response, current sharing configurations, and device PMBus address. More configurations, such as Digital-DC (DDC) bus configuration and fault limits can be easily programmed or changed via the PMBus compliant serial bus interface.

The ISL8272M is a 50A step-down DC/DC power supply module with an integrated digital PWM controller, dual-phase synchronous power switches, inductors, and passives. Only input, output capacitors and minimal passives are needed to finish the design. The 50A of continuous output current can be delivered without a need for airflow or heatsink.
