Here i am designing LED Driver with below requirement and looking for your suggestion and best options.
1.INPUT VOLTAGE RANGE -70-140 VDC / VAC
2 OUTPUT VOLTAGE -15 VDC
3 OUTPUT CURRENT -1-3 Amp
4 OUTPUT CURRENT 2 (WITH DIMMING FUNCTION) -2.5 Amp
5 SURGE PROTECTION -1.8KV, 1.2/50 µsec
6 WORKING TEMP -0°C to 85°C
7 PROTECTION:Short circuit, open circuit, reverse polarity input, over voltage, under voltage, EMI/EMS proof
8 OUTPUT WATTAGE -15VDC X 3 AMP = 45W
