Overview
The ISL91107IRA-EVZ platform allows for a quick evaluation of the high-performance features of the ISL91107IR buck-boost regulator. The ISL91107IRA-EVZ is used to evaluate the ISL91107IRTAZ, featuring adjustable VOUT.
The ISL91107IR is a high-current buck-boost switching regulator for systems using new battery chemistries in a 3mm x 4mm 20-lead 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.
Features
- Small, compact design
- Jumper selectable EN (enabled/disabled)
- Jumper selectable mode (auto PFM/forced PWM)
- Connectors, test points, and jumpers for easy probing
