ISL9444EVAL1Z, ISL9444EVAL3Z

Triple, 180° Out-of-Phase, Synchronous Step-Down PWM Controller Evaluation Boards

Description

The ISL9444EVAL1Z and ISL9444EVAL3Z evaluation boards are used to evaluate the performance of the ISL9444 triple-output synchronous buck controller.

The ISL9444 is a triple-output synchronous buck controller that integrates three PWM controllers. The ISL9444 offers external soft-start, independent enable functions and integrates UV/OV/OC/OT protection. Its current mode control architecture and internal compensation network keep peripheral component count minimal. A programmable switching frequency ranging from 200kHz to 1200kHz helps to optimize inductor size while the strong gate drivers deliver up to 25A for each PWM channel.

Key Features

  • Wide input voltage range: 4.5V to 28V
  • Use lower MOSFET’s rDS(ON) for current sensing
  • Extbias pin to save operating loss
  • Power failure monitor
  • Complete protection: overvoltage, overcurrent, thermal shutdown
  • Three independent power-good indicators

Applications

  • VoX gateway devices
  • NAS/SAN devices
  • ATX power supplies
