概览

The iW3627 is a digital offline PWM controller that provides a constant voltage for smart LED lighting applications up to 90W with high power factor (PF >0.9) and low THD (<20%). It supports the most common single-stage isolated and non-isolated topologies (buck, buck-boost or flyback) as a front-end or standalone power supply in solid-state lighting (SSL) applications with advanced digital control technology.

    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
