Overview

Description

The ISL91128IIN-EVZ platform allows quick evaluation of the high-performance features of the ISL91128 buck-boost regulator. The ISL91128 is a high-current, buck-boost switching regulator for systems using new battery chemistries. 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. It has an I2C interface, which allows the user to access its internal registers for output voltage setting and operation mode control.

Features

  • Small, compact design
  • I2C interface for programmable VOUT, slew rate, and various operation modes (Bypass, Auto-PFM/Forced-PWM)
  • Connectors, test points, and jumpers for easy probing

Applications

Applications

  • Brownout-free system voltage for smartphones and tablet PCs
  • Wireless communication devices
  • 2G/3G/4G RF power amplifiers
