The ISL91110IIA-EVZ evaluation platform allows for quick evaluation of the high performance features of the ISL91110 buck-boost switching regulator. The ISL91110IIA-EVZ evaluates the ISL91110IIAZ featuring resistor programmable output voltage.

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.
