Микросхемы и комплектующие ISL81601FRZ-T7A

DC/DC Controller , Synchronous Buck-Boost, 4.5V to 60V Supply, 1 Output, 575kHz, QFN-32

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.
