DATASHEET ISL81401, ISL81401A 40V 4-Switch Synchronous Buck-Boost Controller FN9310 Rev.1.01 Jan 27, 2022 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 m
ISL81401A Features
* such as OVP, UVP, OTP, and 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 5mmx5mm QFN package to improve thermal dissipation and noise immunity. The unique DE/Burst m
