Evaluation Board | NCL30073LED3GEVB

The NCL30073 is a highly integrated PWM controller capable ofdelivering a rugged and high performance LED converter in a tinyTSOP−6 package. With a supply range up to 24 V, the controller hostsa 65 kHz switching circuitry operated in peak current mode control.When the voltage on FB pin decreases, the controller enters skip cyclewhile limiting the peak current.Over Power Protection (OPP) is a difficult exercise especially whenno−load standby requirements drive the converter specifications. TheON proprietary integrated OPP lets you harness the maximumdelivered power without affecting your standby performance simplyvia two external resistors. An Over Voltage Protection is alsocombined on the same pin but also on the VCC line. They offer anefficient protection in case of adverse open loop operation.Finally, a timer−based short−circuit protection offers the bestprotection scheme, letting you precisely select the protection trip pointwithout caring of a loose coupling between the auxiliary and the powerwindings.
