Fig. 1-2: Example of DCDC Block Board Pattern (Top Layer)
(1) Place the parts to minimize the switching current loop (Figure 1-1: blue line, Figure 1-2: red line).
(2) Route the LX line as short and wide as possible between RC5T619-1xxx and an inductor,
and prohibit adding other redundant lines on it.
(3) Connect the ground line of “Cout” directly to the internal ground plane with multiple vias, in order to
reduce impedance as small as possible. (Target: 50mΩ or less)
(4) Pull out the output of DCDC from near not “L” but “Cout”.
(5) Place “Cin” as close as possible to RC5T619-1xxx.
(Higher priority level is “Cin” < L < “Cout” in the close distance order with RC5T619-1xxx.)
(6) Prohibit routing the VFB line which goes back to the RC5T619-1xxx with parallel to noise source line as
LX, and it's preferable to route the VFB line in the different layer from noise source.
In addition, it should not pass under the Inductors.
