The ISL8120EVAL3Z evaluation board is used for a performance demo of dual independent outputs and DDR applications. And, the ISL8120EVAL4Z evaluation board is used for a performance demo of 2/n-phase single-output applications.

The ISL8120 integrates two voltage mode synchronous buck PWM controllers. It can be used either for dual independent outputs or a 2-phase single output regulator.

Features

  • Output voltage preset to 1.2V/25A (ISL8120EVAL3Z)
  • Output voltage preset to 1.2V/50A (ISL8120EVAL4Z)
  • Input power terminals
  • Output lugs for load connections
  • Input electrolytic capacitors used to handle the input current ripples
  • Two upper and two lower Renesas "speed" series LFPAK MOSFETs are used for each phase
  • 320nH PULSE surface mount inductors are used for each phase
  • Two SANYO POSCAP 2R5TPF470M7L (7mΩ) are used as output E-caps (ISL8120EVAL3Z)
  • Four SANYO POSCAP 2R5TPF470M7L (7mΩ) are used as output E-caps (ISL8120EVAL4Z)
  • Remote sense posts to monitor and evaluate the system voltage regulations
