Overview

The ISL81801EVAL2Z evaluation board features the ISL81801, an 80V bidirectional synchronous buck-boost controller with constant voltage/constant current output. A programmable switching frequency ranging from 100kHz to 600kHz helps to optimize inductor size while the strong gate driver enables high power buck-boost output. This board is designed for high current applications up to 240W.
