WebFeb 9, 2024 · A flyback converter may operate wholly in continuous conduction mode (CCM) when the minimum load current is not too low. However, if the load range also covers quite light currents then, it's likely that the flyback converter will drop into discontinuous conduction mode (DCM). WebThe VPT series primarily uses flyback and forward topologies. They are simple, proven, and reliable. And they can accommodate a wide input voltage range as shown in Table 1. Continuous operation is from 15 or 16V up to 40 or 50V, and transient capability is up to 50 or 80V. This means the DC-DC converter can accommodate most input power ...
