A typical power line filter is shown in Figure 1. The coils of L1 and L2 are wound in the same direction on the same magnetic core. The magnetic flux generated by the two inductors for the differentia...[Details]
Solution:
• Spread out the output current pulses at the same time
• The PCB should be 4 layers or more, and the traces should be as short as possible.
• VLED and VCC are sep...[Details]
