Page 2: Theory Of Operation
NCL30073LED4GEVB THEORY OF OPERATION Power Stage The power stage operates as a fixed frequency DCM The power stage is a flying buck boost design. In this power stage. The DCM allows for no forced commutation configuration, drain of the switching FET is connected to the of the output diode for good EMI performance. - Page 3 33nF 400V MOV 250V − Rdamp MB6S AC_N Figure 3.
