WebDCM or on the edge of DCM/CCM operation, referred to as transition mode (TM) or critical conduction mode. Figure 2 shows the difference between the drain-to-source waveform of a DCM flyback that does not switch on the resonant valley and a TM flyback that does switch on the resonant valley. WebNon-resonant mode SMPS circuits rely on hard-switching techniques. As such, Infineon offers 2 types of resonant mode controller ICs, namely hybrid flyback (or commonly known as asymmetric half-bridge flyback topology) and LLC controllers. Both types of resonant controllers share similarities such as utilizing an external capacitor as well as ...
