Page 2: Theory Of Operation
NCL30073LED2GEVB THEORY OF OPERATION Power Stage provides for a constant power control over a large portion of The power stage is a flyback design. The power stage the input waveform. The resistor divider of R27 and R29 operates as a fixed frequency DCM power stage. The DCM provides some wave shaping to improve the power factor. - Page 3 NCL30073LED2GEVB SCHEMATIC +HVDC_iso AC_L 100nF 400V 10mH 33nF 400V MOV 250V − MB6S Rdamp AC_N Figure 3.
