The ISL81802EVAL2Z dual-output evaluation board features the ISL81802, an 80V dual synchronous buck controller that offers external soft-start, independent enable functions and integrates UV/OV/OC/OT protections. A programmable switching frequency ranging from 100kHz to 1MHz helps to optimize inductor size while the strong gate driver delivers up to 10A for each output. The ISL81802EVAL2Z board is designed for high current applications.
