Note: To meet conducted emissions regulations, L102 and L201 must be oriented
orthogonally (e.g., L102 radial and L201 axial lying down) AND spatially separated with at
least a 0.75cm air gap between the inductor bodies (alternatively, any relative orientation
and at least 1.5cm spacing may be used).

Note: Diode bridge D203 is used to compensate for the positive temperature
coefficient of the Zener diode D202. It functions the same as two forward-biased
diodes in series, but does so with only one package. D202 and D203 must
have tight thermal coupling for the compensation to work effectively. Locate
the two diodes close together and place a copper pad that connects to
the "PSA" net under both devices.
