Abstract
An electronic circuit includes a common mode choke coil (CMCC), a first capacitor and a second capacitor as a pair of line bypass capacitors, and a DC-DC converter coupled to a power line and also to a ground line coupled to a ground of a substrate. The first capacitor is coupled to the power line between the CMCC and the DC-DC converter. The first capacitor is coupled between the power line and a metal housing. The second capacitor is coupled to the ground line between the CMCC and the DC-DC converter. The second capacitor is coupled between the ground line and the metal housing.
