ISL8274MEVAL1Z

The ISL8274MEVAL1Z from Intersil is a 30A/30A dual-channel digital PMBus step-down power module evaluation board. It provides all circuitry required to evaluate the features of the ISL8274M. A majority of the features of the ISL8274M such as compensation-free ChargeMode™ control, soft-start delay and ramp times, supply sequencing and voltage margining are available on this evaluation board. For sequencing evaluation, the board can be connected to any digital module evaluation board that supports the DDC bus. This evaluation board comes with a placeholder for pin-strap resistors to adjust output voltage, switching frequency, input Undervoltage Lockout (UVLO) protection threshold, device PMBus address, overcurrent limit, ASCR setting and soft start setting. More configurations can be easily programmed or changed using a PMBus compliant serial bus interface.
