ISL8274MEVAL1Z

Evaluation-board to evaluate the features of the 30A/30A dual-channel digital PMBus step-down power module. This Evaluation-board is a 4in x 4.5in 8-layer FR4 board with 2oz. copper on the top and bottom layers and 1oz. copper in the buried layers. 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. For sequencing evaluation the board can be connected to any digital module Evaluation-board that supports the DDC bus. Suitable for use at General purpose power for ASIC, FPGA, DSP, memory, industrial/ATE and networking equipment, server, telecom, storage and datacom.
