Description

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.
