Description

The ISL91108IIA-EVZ evaluation platform allows for quick evaluation of the ISL91108 highly-integrated buck-boost switching regulator that accepts input voltages either above or below the regulated output voltage. Unlike other buck-boost regulators, this regulator automatically transitions between operating modes without significant output disturbance. The ISL91108 is designed for standalone applications and supports a 3.3V fixed output voltage or variable output voltages with an external resistor divider. Output voltages as low as 1V or as high as 5.2V are supported using an external resistor divider.

Features

  • ISL91108 high-efficiency buck-boost regulator
  • Input voltage rating from 1.8V to 5.5V
  • Resistor programmable output voltage on the ISL91108IIA-EVZ evaluation board
  • Up to 1.5A output current (PVIN = 3.0V, VOUT = 3.3V)
  • 2.5MHz switching frequency
  • Jumper selectable EN (enabled/disabled)
  • Jumper selectable mode (auto-PFM/forced-PWM)
  • Connectors, testpoints and jumpers for easy evaluation

Applications

  • Smartphones
  • Tablet PCs
