Overview

The ISL6440EVAL1Z evaluation board highlights the operation of the ISL6440 300kHz dual, 180° out-of-phase, step-down pulse width modulation (PWM) controller in an embedded DC/DC converter application. The ISL6440 is a high performance triple-output controller that offers control and protection features for two synchronous buck PWMs.

ISL6440EVAL1Z Buck PWM Controller Eval Board
ISL6440EVAL1Z Buck PWM Controller Eval Board
  • Wide input supply voltage range: 5.6V to 24V, 4.5V to 5.6V
  • Two 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)
  • 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

Applications

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

    Parametric Table tips

    Tips for Using This Parametric Table:

    • Hide Filters button in header: Collapse or expands filters
    • Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
    • Reset button in header: Reset all filters to the page default
    • Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
    • Export button in header: Export the filtered results of the table to an Excel document
    • Filter parts search bar in header: Type to filter table results by part number
    • Hide column button in column headers: Select to hide columns in table
    • AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
    • Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
