PRODUCTION DATA
The boost converter components must be positioned close to the VLX, VBST, and PGND pins. To minimize switching noise, ensure that the VLX trace is as short as possible. A PGND plane can assist with connecting the PGND connections together, but may not be necessary if the PGND routing is short enough without the PGND plane. All PGND routing must remain separated from the AGND plane. Connect PGND to AGND at a single point near the AGND pin.
