NCL30073 Current-Mode PWM Controller

Pin # Pin Name Function Pin Description 1 OPP Adjust the Over Power A resistive divider from the auxiliary winding to this pin sets the OPP compensation Protection level. When brought above 3 V, the part enters auto *recovery mode. 2 FB Feedback pin A voltage variation on this pin.
NCL30073 Current-Mode PWM Controller for LED Application The NCL30073 is a highly integrated PWM controller capable of delivering a rugged and high performance LED converter in a tiny TSOP 6 package. With a supply range up to 24 V, the controller hosts a 65 kHz switching circuitry operated in peak current mode control. When the voltage on FB pin decreases, the controller enters skip cycle while limiting the peak current. Over Power Protection (OPP) is a difficult exercise especially wh.
