IC revision1

Description

The ISL81801DEMO1Z demonstration board (shown in Figure 8) features the ISL81801, a 80V high voltage synchronous buck-boost controller that provides external soft-start, independent enable functions, and integrates UV/OV/OC/OT protection. Programmable switching frequency ranging from 100kHz to 600kHz helps to optimize the inductor size while the strong gate driver delivers up to 20A for the buck-boost output.
