RT6214A/B
Layout Considerations
Follow the PCB layout guidelines for optimal
performance of the device.
components away from the LX node to prevent stray
capacitive noise pickup.
Keep the traces of the main current paths as short
Connect feedback network behind the output
capacitors. Keep the loop area small. Place the
feedback components near the device.
and wide as possible.
Put the input capacitor as close as possible to VIN
pin.
An example of RT6214A/B PCB layout guide is
shown in Figure 9 and Figure 10 for references.
LX node is with high frequency voltage swing and
should be kept at small area. Keep analog
