LED Power Supply

Question asked by mattoo.anuj on Nov 22, 2016
Can anybody suggest me reference design for driving LEDs array along with micro controller.

Here is my requirement :-

       
  • Output 1 :- 17V, 400mA (Constant Current)
  •    
  • Output 2 :- 3.3V, 1A (Constant Voltage)
  •    
  • Power :- 12W
  •    
  • Isolated supply
  •    
  • OFF-Line
  •    
  • Constant current and voltage
I had designed the supply using some reference document using VIPER22a. But it has single output only and is not reliable at all. 

Please suggest me some designs.
