ISL9440xEVAL1Z

Triple, 180° Out-of-Phase, Step-Down PWM and Single Linear Controller Evaluation Boards

Description

The ISL9440xEVAL1Z evaluation boards are used to evaluate the performance of the ISL9440A, ISL9440B and ISL9440C quad-output synchronous buck controllers.

The ISL9440A, ISL9440B and ISL9440C are quad-output controllers that integrate three PWM synchronous buck controllers and one low-dropout linear regulator controller. The ISL9440A offers internal soft-start, independent enable functions and integrates UV/OV/OC/OT protection. While the ISL9440B and ISL9440C offer programmable soft-start, independent enable functions and integrate OV/OC/OT protection. All three devices offer current mode control architecture and an internal compensation network, keeping peripheral component count minimal.

Key Features

  • DC/DC, step-down with LDO
  • Current - output: 6A, 6A, 4A, 800mA
  • Switching frequency (ISL9440A and ISL9440C): 600kHz
  • Switching frequency (ISL9440B): 300kHz
  • Soft-start timing (ISL9440A): 1.7ms
  • Soft-start timing (ISL9440B and ISL9440C): Programmable
  • Voltage - input: 6V to 16V

Applications

  • Satellite and cable set-top boxes
  • Cable modems
  • VoX gateway devices
  • NAS/SAN devices
  • ATX power supply (ISL9440B and ISL9440C)
