Product Overview

The NCP1028LEDGEVB is an evaluation board to evaluate NCP1028 integrated fixed frequency current mode controller with a 5.8ohm, 700V MOSFET. The NCP1028 contains soft start, frequency jittering, skip cycle etc to build a rugged and low cost power supply. The NCP1028LEDGEVB is a universal input ( 90vac to 265Vac) LED driver designed for constant current applications. This evaluation board has been configured in an isolated flyback topology with secondary side constant current control and it has been preconfigured to source a nominal current of 720mA. 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.
  • Skips cycles on low power demand
  • Short circuit protection independent of the AUX winding
  • Overpower protection
  • Fixed peak current of 800mA
  • Internal current source for clean and lossless start up sequence
  • Programmable brown out input for low input voltage detection
  • Input to permanently latch off the part
  • Internal frequency jittering for improved EMI signature
  • Programmable over power protection
  • Medium power AC to DC power supply for CE apparatus
