Design Requirements for non-dimmable LED Driver

Question: What are the key design requirements for a constant current LED driver using CY8CLEDAC01?




The key input parameters to design a constant current LED driver using CY8CLEDAC01 are:

  1.   LED current, IOUT
  2.   LED maximum voltage, VOUT (Max)
  3.   Input voltage and range, VLINE, VLINE (Min), VLINE (Max)
  4.   Line frequency and range, FLINE
  5.   Desired system efficiency

In addition to the above key specs, it is also important to understand the EMC (electro-magnetic compatibility) compliance specifications for the region where the end product is intended to be sold.
