ISL8120EVAL3Z, ISL8120EVAL4Z

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

Description

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.

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

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
  • 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

Applications

  • Power supply for datacom/telecom and POL
  • Paralleling power module
  • Wide and narrow input voltage range buck regulators
  • DDR I and II applications
  • High current density power supplies
  • Multiple outputs VRM and VRD
