Driver circuit for organic LED (LED) using a flyback converter with a primary switch (Q1) and a power transformer (T2), whereby the primary switch (Q1) is clocked with high frequency and the power transformer (T2) is transferring the energy to a secondary side, whereby on the secondary side a active rectifier switch (Q2) is applied for the supply of the organic LED (LED), characterized by an inductive driving element (T1, L1), which is not magnetically coupled to the power transformer (T2), where the inductive driving element (T1, L1) is using the current flow through the primary switch (Q1 ) to turn off the active rectifier switch (Q2). |
