概要

The ISL6729 pulse width modulating (PWM) current mode controller is designed for power conversion applications that are based on a microcontroller, or other device, which can generate a digital clock signal at the desired switching frequency. Similar to the ISL684x family of products, the ISL6729 provides the basic current mode PWM control features, but eliminates the error amplifier, the oscillator, and the reference. An external clock signal applied to the oscillator input provides the time base and sets the maximum duty cycle. The reduced feature set is ideal for those applications where a microcontroller is available to provide the monitor and control functions. The analog PWM provides the cycle-by-cycle peak-current mode control, leaving the monitor and control overhead to the microcontroller.

    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
