Zusammenfassung:	A resonant hybrid flyback converter (10) for a LED-based load (13c) is provided. Said resonant hybrid flyback converter (10) comprises a half-bridge (11) comprising a high-side switch (11a) and a low-side switch (11b), a flyback resonant tank (12) comprising a transformer with a primary side (15a) and a secondary side (15b), and a processing unit (14). In this context, the half-bridge (11) is configured to supply said primary side (15a). Additionally, the secondary side (15b) is configured to supply the LED-based load (13c). Furthermore, the processing unit (14) is configured to receive at least one feedback signal based on a sensed secondary side current with respect to the secondary side (15b). Moreover, the processing unit (14) is configured to control an on-time of the low-side switch (11b) and/or an on-time of the high-side switch (11a) on the basis of the at least one feedback signal.
