Customer Specific Device from ON Semiconductor DAP006 PWM Current−Mode Controller for Free Running Quasi−Resonant Operation The DAP006 combines a true current mode modulator and a demagnetization detector to ensure full borderline/ critical Conduction Mode in any load/line conditions and minimum drain voltage switching (Quasi−Resonant operation). Due to its inherent skip cycle capability, the controller enters burst mode as soon as the power demand falls below a predetermined level. As this happens at low peak current, no audible noise can be heard. An internal 5.0 ms timer prevents the free−run frequency to exceed the 150 kHz CISPR−22 EMI starting limit while the skip adjustment capability lets the user select the frequency at which the burst foldback takes place.
