The ISLACDC750WEVKIT1Z evaluation kit is designed to demonstrate ATX PC power supply applications based on the ISL6754 ZVS full-bridge PWM controller, ISL6731A and ISL6731B power factor correction (PFC) controllers, and the ISL6721 single-ended current mode PWM controller. With a 400V DC bus, the converter can output 12V at 62.5A. The efficiency performance can reach upward of 80%. Overall protection functions such as input overvoltage and undervoltage protection, output overvoltage, overcurrent, over-temperature, and short circuit protection make the circuit very reliable. The PSON pin provides an interface to remotely control the board, and a power-good (PG) pin indicates the working condition of the circuit. The circuit can also be adapted to a battery charger.
