Overview
Description
The ISL91127IIN-EVZ, ISL91127II2A-EVZ and ISL91127IIA-EVZ platforms allow quick evaluation of the high-performance features of the ISL91127 buck-boost regulator series. The ISL91127IIN-EVZ evaluates the ISL91127IINZ with fixed 3.3V 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 (2.15mmx1.74mm) package. It uses Intersil’s 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 ISL91127IIA-EVZ
- Fixed 3.3V output voltage on the ISL91127IIN-EVZ
- Fixed 3.5V output voltage on the ISL91127II2A-EVZ
Applications
- Handheld and battery powered consumer and medical devices
- Brownout free system voltage for smartphones and tablet PCs
- Wireless communication devices
- 2G/3G/4G RF power amplifiers
