Overview
Description
The ISL91127IRA-EVZ platform allows for quick evaluation of the high-performance features of the ISL91127IR buck-boost regulator.
The ISL91127IR is a high-current buck-boost switching regulator for systems using new battery chemistries in a 20 Ld, 0.5mm pitch QFN (4mm x 4mm) 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
- Resistor programmable output voltage on the ISL91127IRA-EVZ
