Средства разработки интегральных схем (ИС) управления питанием ISL8117DEMO2Z

DEMO BOARD , SYNC BUCK CONTROLLER

Demonstration board features the ISL8117. The ISL8117 is a 60V high voltage synchronous buck controller that offers external soft-start, independent enable functions and integrates UV/OV/OC/OT protection. Its current mode control architecture and internal compensation network keep peripheral component count minimal. Programmable switching frequency ranging from 100KHz to 2MHz helps to optimize inductor size while the strong gate driver delivers up to 30A for the buck output. Demonstration board is designed for high current applications. The current rating of the ISL8117DEMO2Z is limited by the FETs and inductor selected. The ISL8117 gate driver is capable of delivering up to 20A for the buck output as long as the proper FETs and inductor are provided.
