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 when no−load standby requirements drive the converter specifications. The ON proprietary integrated OPP lets you harness the maximum delivered power without affecting your standby performance simply via two external resistors.
