ISL81401AEVAL1Z, Evaluation Board, ISL81401AFRZ, Synchronous Buck-Boost Controller, Power Management

ISL81401AEVAL1Z is a high voltage buck-boost controller evaluation board. It features the ISL81401A, a 40V high voltage synchronous buck-boost controller that offers external soft-start, independent enable functions, and integrates UV/OV/OC/OT protection. A programmable switching frequency ranging from 100kHz to 600kHz helps to optimize the inductor size while the strong gate driver delivers up to 20A for the buck-boost output. The ISL81401AEVAL1Z evaluation board is designed for high current applications. The current rating of the ISL81401AEVAL1Z is limited by the FETs and inductor selected. Application includes battery backup, type-C power supply and chargers, battery powered industrial applications, aftermarket automotive redundant power supplies, robots and drones, medical equipment, security surveillance.
