概要

The iW338 is a generic PWM signal generator IC that converts a 0V to 0.6V analog voltage to an inverted 0% to 100% PWM duty cycle. The PWM frequency range is set by an external capacitor and can be programmed from 100Hz to 50kHz. The output of the iW338 is a 5V PWM driver capable of driving an external optocoupler or MOSFET.

    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
