概要

The RTKA212832DR0000BU provides a simple platform to demonstrate the performance of RAA212832, a synchronous buck regulator with 2 LDO outputs. The evaluation board can support a wide input voltage range of 14V to 72V. The buck output is 12V capable of 500mA. The buck output is used as the input for the 5V 100mA and 3.3V 50mA LDO outputs. The buck output can also be set to 6V to further reduce power dissipation on the LDO rails.

    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
    • Document icon next to product name in row: View the featured document for this product
    • Chip icon next to the right of the document icon in row: View the block diagram for this product
    • Cart icon to the right of the chip icon: Indicates that samples are available for this product
