<p>Switching regulator structures split single magnetic loops into multiple magnetic loops (24, 25), with linked opposing magnetic fields, to cause a cancelling effect, resulting in a much lower overall magnetic field. Synchronously switched transistors (14A, 14B) are divided up into parallel topside transistors and parallel bottomside transistors. The topside transistors are positioned to oppose the bottomside transistors, and bypass capacitors (20A, 20B) are connected between the pairs to create a plurality of current loops. The components are arranged to form a mirror image of the various current loops so that the resulting magnetic fields are in opposite directions and substantially cancel each other out. Creating opposite current loops (52, 54, Fig 6 not shown) may also be achieved by forming the conductors and components in a figure 8 pattern with a cross-over point.</p> |
