Bidirectional buck-boost, dual-phase buck DC/DC controllers handle 48-V apps

November 18, 2020 By Redding Traiger Leave a Comment

The ISL81801 buck-boost controller acts as a “UPS on a chip” by enabling bidirectional current flow (forward or reverse) using constant-voltage and constant-current regulation. This allows a battery or supercapacitor to be charged and discharged using a single controller and power path. The ISL81801’s combination of the industry’s highest 80V buck-boost switching frequency (600 kHz) […]
