Design Requirements for non-dimmable LED Driver
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:
- LED current, IOUT
- LED maximum voltage, VOUT (Max)
- Input voltage and range, VLINE, VLINE (Min), VLINE (Max)
- Line frequency and range, FLINE
- 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.
