The conducted emissions are tested to the CISPR 25 class 5 and Toyota TSC 0505G:2019 standards. The CISPR 25 class 5 and Toyota TSC 0505G:2019 compliance were achieved without a common-mode choke. The waveforms of EMI test results are shown in following images.

Figure 2-4 and Figure 2-5 illustrate CISPR 25 Class 5 EMI performance from 150 kHz to 108 MHz, and the data was also collected under the following conditions:

• V_IN = 12 V
• I_O = 3 A
