Layout guidelines and design recommendations

A proper printed circuit board layout is essential for correct operation of any switch-mode

converter and this is true for the VIPer0P as well. The main reasons to have a proper PCB

layout are:



Provide clean signals to the IC, ensuring good immunity against external noises and

switching noises



Reduce the electromagnetic interferences, both radiated and conducted, to pass more

easily the EMC

When designing a SMPS using VIPer0P, the following basic rules should be considered:



Separating signal from power tracks: generally, traces carrying signal currents

should run far from others carrying pulsed currents or with quickly swinging voltages.

Signal ground traces should be connected to the IC signal ground, SGND, using a
