ISL81801 80V Bidirectional 4-Switch Synchronous Buck-Boost Controller

Datasheet ISL81801 80V Bidirectional 4-Switch Synchronous Buck-Boost Controller The ISL81801 is a true bidirectional 4-switch synchronous buck-boost controller with peak and average current sensing and monitoring at both ends. With wide input and output voltage ranges, the controller is suitable for industrial, telecommunication, and after-market automotive applications. The ISL81801 uses a proprietary buck-boost control algorithm with valley current modulation for Boost mode and peak current .

ISL81801 Features

* such as OVP, UVP, OTP, average and peak current limit on both input and output to ensure high reliability in both unidirectional and bidirectional operation. The IC is packaged in a space-conscious 32 LD 5mm x5mm TQFN package or easy to assemble 4.4mmx9.7mm 38 LD HTSSOP package. Both packages use an
