00 Sep 11, 2018 The ISL81401 and ISL81401A are 4-switch synchronous buck-boost controller with peak and average current sensing and monitoring at both ends.
The ISL81401 is a bidirectional device that can conduct current in both directions while the ISL81401A is an unidirectional device.
The ISL81401 and ISL81401A use the proprietary buck-boost control algorithm with valley current modulation for Boost mode and peak current modulation for Buck mode control.
The ISL81401 and ISL81401A have four independent control loops for input and output voltages and currents.
Inherent peak current sensing at both ends and cycle-by-cycle current limit of this family of products ensures high operational reliability by providing instant current limit in fast transient conditions at either ends and in both directions.
It also has two current monitoring pins at both input and output to facilitate Constant Current...
