Description

ISLACDC750WEVKIT1ZUG043 Rev.0.00 May 17, 2017Consist 5 boards:MOTHERBOARD ISLACDC750W-MBEV1ZISL6721-DB-1ZISL6731-DB-1ZISL6754DBEVAL2ZThe ISLACDC750WEVKIT1Z utilizes an active PFC and asymmetrical full-bridge ZVS converter and targets ATX PC power supply applications. 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 the user with an interface to remote control the board, while a Power-Good (PG) pin indicates the working condition of the circuit. The circuit can also be adapted to a battery charger. The ISLACDC750WEVKIT1Z consists of a motherboard ISLACDC750W-MBEV1Z, and 3 daughter boards, namely ISL6731X-DB-1Z, ISL6721-DB-1Z and ISL6754DBEVAL2Z. They will be referred to as MB, PFDB, BiasDB, and ZVSDB, respectively. Boost PFC and asymmetrical Full-Bridge ZVS converter (Alan)
