ISL81401EVAL1Z

Synchronous buck-boost controller evaluation board. This board features the ISL81401 synchronous buck-boost controller that offers external soft-start, independent enable functions and integrates UV/OV/OC/OT protections. A programmable switching frequency ranging from 100kHz to 600kHz helps to optimize inductor size while the strong gate driver delivers up to 20A for the buck-boost output. Typical applications include battery backup, Type-C power supply and chargers, battery powered industrial applications, aftermarket automotive, redundant power supplies, robots and drones, medical equipment, security surveillance.
