V& w* G) v/ A5 F: I( Q$ q: eNot placing ground layer directly below the inductor (Figure 6-c) is also a point to pay attention to, when placing inductor. Due to the eddy current occurring in the ground layer, the inductor value decreases and the loss increases (decrease of Q) with set-off effect from line of magnetic force. Signal line other than ground also has the possibility of propagating switching noise caused by eddy current. It is better to avoid wiring directly under inductor. If wiring is unavoidable, please use closed magnetic circuit structured inductor with small leak from line of magnetic force.
