Renesas Electronics High Voltage Buck-Boost Controller Evaluation Board for ISL81601

The Renesas Electronics ISL81601EVAL1Z evaluation board 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. It is a true bidirectional 4-switch synchronous buck-boost controller with peak and average current sensing and monitoring at both ends. The ISL81601 has four independent control loops for input and output voltage and current. Inherent peak current sensing at both ends and the cycle-by-cycle current limit of this family of products ensures high operational reliability by providing an instant current limit in fast transient conditions at either end and in both directions. A 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.
