DATASHEET ISL91110 High Efficiency Buck-Boost Regulator with 4.5A Switches FN8434 Rev 4.00 February 5, 2016 The ISL91110 is a high-current buck-boost switching regulator for systems using new battery chemistries. It uses Intersil’s proprietary buck-boost algorithm to maintain voltage regulation while providing excellent efficiency and very low output voltage ripple when the input voltage is close to the output voltage. The ISL91110 is capable of delivering at least 2A continuous output curren.
