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 modulation for Buck mode control.
The ISL81801 has four independent control loops for input and output voltages and currents.
Inherent peak current sensing at both ends and cycle-by-cycle current limi...
