Layout Recommendations
As with all switching DC/DC converter, care must be
observed to the PCB board layout and component
placement. To prevent electromagnetic interference (EMI)
problems and reduce voltage ripple of the device any
copper trace which see high frequency switching path
should be optimized. So the input and output bypass
ceramic capacitor, C
and C
as depicted Figure 2 must
IN
OUT
be placed as close as possible the NCP5010 and connected
directly between pins and ground plane. In additional, the
track connection between the inductor and the switching
input, SW pin must be minimized to reduce EMI radiation.
Finally it is always good practice to keep way sensitive
tracks such as feedback connection from switched signal
like SW or VOUT connections. Figure 28 shown an
example of optimized PCB layout.
