ISL81802EVAL3Z

80V dual synchronous buck controller evaluation board. The ISL81802EVAL3Z four phase 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 40A for the buck output. The board is designed for high current applications.
