Hi Team,
I would like to know if buck converter could be work as LED drive.
Vin = 20-36V Vout = 18V Iout=1A
We have experiment and LED could be brighten. (Vin= 20V)
But when Vin = 24.1V-25.2V the LED become flicker. And when Vin is higher than 25.3V, the LED isn't flicker. (25.3-36 is normal)
Why LED flicker when Vin = 24.1V-25.2V but normal when Vin = 20V-24V and 25.3V~36V
Regards,
Roy
