Overview

The ISL81601EVAL1Z evaluation board features the ISL81601, a 60V high voltage synchronous buck-boost controller that offers external soft-start and 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.
