概述
描述
The ISL91127II2A-EVZ evaluation platform allows for quick evaluation of the high-performance features of the ISL91127 buck-boost regulator. The ISL91127II2A-EVZ evaluates the ISL91127II2AZ with a fixed 3.5V output voltage.
The ISL91127 is a high-current buck-boost switching regulator for systems using new battery chemistries in a 20-bump, 0.4mm pitch WLCSP (2.15mm x 1.74mm) 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.
