I'm looking to choose a LED driver for our application. In the above mentioned LED driver, in the application section, I see this statement:
"The value of the output capacitor C6 was selected to give peak-to-peak LED ripple current equal to 30% of the mean value"
1. What kind of capacitor (Electrolytic/Film) should i use to achieve this figure? If electrolytic, what is the lifetime of my design? It will be limited by the electrolytic cap right?
2. Just to confirm with my internal spec, when I use this capacitor, my Peak to Avg ratio of the Output will be around 1.2?
