Overview

The ISL91107IRN-EVZ platform allows for a quick evaluation of the high-performance features of the ISL91107IR buck-boost regulator. The ISL91107IRN-EVZ is used to evaluate the ISL91107IRTNZ featuring 3.3 Vout.

The ISL91107IR is a high-current buck-boost switching regulator for systems using new battery chemistries in a 3x4 20 Ld TQFN package. 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.
