ISL6443AEVAL2Z

300kHz, Dual, 180° Out-of-Phase, Step-Down PWM and Single Linear Controller Evaluation Board

描述

The ISL6443AEVAL2Z evaluation board highlights the operation of the ISL6443A 300kHz, dual, 180° out-of-phase, step-down pulse width modulating (PWM) and single linear controller in an embedded DC/DC converter application. The ISL6443A is a high performance triple-output controller offering control and protection features for two synchronous buck PWMs and one linear regulator.

主要特性

  • Wide input supply voltage range: Variable 5.6V to 24V, fixed 4.5V to 5.6V
  • Three independently programmable output voltages
  • Switching frequency 300kHz
  • Out-of-phase PWM controller operation reduces required input capacitance and power supply induced loads
  • No external current sense resistor - Uses lower MOSFET's rDS(ON)
  • Bidirectional frequency synchronization for synchronizing multiple ISL6443A ICs
  • Programmable soft-start
  • Extensive circuit protection functions
    • PGOOD
    • UVLO
    • Overcurrent
    • Over-temperature
    • Independent shutdown for both PWMs
  • Excellent dynamic response - Voltage feed-forward with current mode control

应用

  • Power supplies with multiple outputs
  • xDSL modems/routers
  • DSP, ASIC and FPGA power supplies
  • Set-top boxes
  • Dual output supplies for DSP, memory, logic, microprocessor (µP) core, and I/O
  • Telecom systems
