We build the DER337 and it works even better then expected!
Now we added a potmeter to set the output current.
As result we see that the driver makes steps up/down (about 50mA) to create the output current.
Question 1: How can we modify the step-size to 10mA?
When we change the input voltage we see the driver starts to correct the output current by making steps up/down. As result we see a litle change in LED-light. Also on the LED-current we see a short over-/under shoot.
Question 2: What is the best way to minimize this over-/undershoot?
Thanks inadvance for all usefull respons.
