I've read the application note for LinkSwitch-PH family and some its design examples but I didn't get how to dim the loaded LEDs? (I mean changing which element will decrease/increase the LED brightness? Since I couldn't find any variable element!)
Another question, I am supposed to design a LED driver and expected dimmable range is 10%-100% (i.e. 10:1). Is it right to configure the device with non-dimming mode (i.e. setting R resistor to 24.9 Kohm and ...) ?
Quoting from AN-49, page 2:
"The normal (non-dimming) mode provides input line voltage compensation that maintains output current regulation within narrow limits (<±10%) across universal input voltage ranges (e.g. 90 VAC – 265 VAC). This mode does not prevent the device from being used with AC phase dimmers however dimming range is reduced (10:1)."
Kindly, explain your answer by this application note:
