Note: C1 through C4 can be 0.01 µF to 0.1 µF. Select the voltage rating to meet input-to-output isolation requirements. C5 should be the
recommended value indicated in the power module data sheet.

Note: Vdc input(+) and Vdc input(–) planes should overlay each other, as should the VI(+) and VI(–) planes, as should the VO(+) and VO(–)
planes. Avoid routing signals or planes under the power module or the filter module. Ensure all connections are low impedance.
