概要

The ISL6539EVAL2 evaluation board is used to evaluate the ISL6539 wide input range, dual pulse width modulation (PWM) controller with DDR option. The evaluation board supports testing with laboratory power supplies. Both regulated outputs can be exercised through external loads. There are posts available on the two regulated output rails for drawing a load and/or monitoring the voltages.

The ISL6539EVAL2 has two LEDs which indicate the status of the individual channel power-good (PGOOD) signals. There are also four scope probe points that allow for in-depth analysis. Four jumpers have also been provided for control and monitoring purposes.

    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
