Overview

The ISL91110IIN-EVZ evaluation platform allows for quick evaluation of the high-performance features of the ISL91110 buck-boost switching regulator. The ISL91110IIN-EVZ evaluates the ISL91110IINZ featuring 3.3 Vout.

The ISL91110 is a high-current buck-boost switching regulator for systems using new battery chemistries. It uses Renesas' 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.
