Overview

The ISL81807EVAL1Z dual-phase evaluation board features the ISL81807, an 80V high voltage dual synchronous 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 2MHz helps to optimize inductor size while the strong gate driver delivers up to 240W for the boost output. The ISL81807EVAL1Z  board is designed for high current applications.
