Other Parts Discussed in Thread: , TPS92561
I am designing a luminaire with LEDs (VF=6.1V, IF=100mA) using LM3492 based on following:
- Vin= 24Vac to 32Vac
- Iout (300mA) , Vout (42.7V)
I am currently implementing the configure 7 series 3 parallel to LM3492AR111DEMO board. I can get good output but not a good power factor and effieciency.
Is there any suggestion to improve the power factor? Next, is ther any formula to calculate the value of ILIM and IREF?
