NCP1207DR2 - Brand New onsemi AC DC Converters, Offline Switchers
-
Product Details
__
The NCP1207 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 8.0 s timer prevents the free−run frequency to exceed 100 kHz (therefore below the 150 kHz ISPR−22 EMI starting limit), while the skip adjustment capability lets the user select the frequency at which the burst foldback takes place.
