Abstract
The invention relates to a synchronous flyback converter () having terminals for supplying an LED load. The synchronous flyback converter () comprises a sensing winding (L) coupled to a primary winding (L) of a transformer T of the flyback converter (), a control unit () controlling a primary side switch (S) in series to the primary winding (L) of the flyback converter () using a feedback signal for a closed loop control of a secondary side voltage of the flyback converter () by controlling the frequency and/or duty cycle of the switching of the primary side switch (S), wherein the feedback signal is derived from a sensing voltage across the sensing winding (L) sampled once during a switch-on time of a secondary side switch (S) of the flyback converter ().
