ISL81601EVAL1Z: 12V @ 10A, 9 ~ 60V in, Bidirectional 4-Switch Synchronous Buck-Boost Controller

Summary

The 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. A programmable switching frequency ranging from 100kHz to 600kHz helps to optimize inductor size.

The ISL81601 is a true bidirectional 4-switch synchronous buck-boost controller with peak and average current sensing and monitoring at both ends. Its wide input and output voltage ranges make it suitable for industrial, telecommunication, and after-market automotive applications.

The ISL81601 uses the proprietary buck-boost control algorithm with valley current modulation for Boost mode and peak current modulation for Buck mode control.

High light-load efficiency in pulse skipping DEM operation
Programmable soft-starto Optional DEM/PWM operation
Optional CC/HICCUP OCP protection
Supports prebias output with soft-start
Back biased from output to improve efficiency
