ISL81801 Datasheet (Renesas) - 80V Bidirectional 4-Switch Synchronous Buck-Boost Controller

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
