LM723 regulator
« on: July 09, 2014, 02:18:19 am »
hey  :-+ friends,
                  I am working on a project where I need current control regulator to drive leds (5W) and I came across LM723 which has current control inside, I understand how it works but I don't know how to design it for specific current value. I had a look on its TI datasheet but it didn't helped much. Please if some one can help me over this.

If you know any more IC's with CC regulator in it and which is widely available, please do share. Thank You.
Find me and things I'm working on -

Hi yashrk.

The standard LM317 can be used as a simple current source suitable for driving LEDs - there are details in the datasheet as well as many examples on the web.

If your requirements are more complex, please provide some additional detail - it will help more knowledgeable forum members to provide better targeted assistance.

LM317 is much simpler to implement a CC source compared to the 10 pin LM723. Also the LM723 cannot control much current without external power transistor.
