Dual/n-Phase Buck PWM Controller with Integrated Drivers Evaluation Boards


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.

Key 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
