NCP1028LEDGEVB: 720 mA 18 V LED Driver Evaluation Board
The NCP1028LEDR2GEVB is a universal input ( 90 to 265 Vac) LED Driver designed for constant current applications. This demo board has been configured in an isolated flyback topology with secondary side constant current control. This board has been preconfigured to source a nominal current of 720 mA. The design has open circuit output protection which clamps the output to voltage of 18V. In a universal input flyback configuration, the NCP1028 is limited to approximately 15W. The current and open circuit voltage can be changed by simply changing out a resistor zener combination. The NCP1028 is an integrated fixed frequency current-mode controller with a 5.8 ohm (typ) 700 V MOSFET. It contains all necessary features such as soft start, frequency jittering, skip cycle etc. to build a rugged and low cost power supply.
