Description

The ISL81601DEMO1Z demonstration board (shown in Figure 8 on page 9) features the ISL81601, a 60V high voltage synchronous buck-boost controller that offers external soft-start, independent enable functions, and integrates UV/OV/OC/OT protection. Programmable switching frequency ranging from 100kHz to 600kHz helps to optimize inductor size while the strong gate driver delivers up to 20A for the buck-boost output.
