ISL91127IRN-EVZ, ISL91127IRA-EVZ

High Efficiency Buck-Boost Regulators with 4.5A Switches Evaluation Boards

Description

The ISL91127IRN-EVZ and ISL91127IRA-EVZ platforms allow 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. 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.

Key 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
  • Fixed 3.3V output voltage on the ISL91127IRN-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
