Hi,
I have a working board with a DC-DC step up with a LM2577-ADJ. Some more info:
- input voltage: 12V
- output voltage: 13V-19V
- output current: up to 2A
The output voltage is selected by a digital potentiometer inserter in the feedback voltage divider.
I want to add a current limiter in order to lower the output voltage if the output current grow over 2A.
What's the best way to achieve this?
I can change the IC with another but I need a TO220 package and the same configuration. In other words, it should be nice a similar DC-DC with the Isense input pin.
May you suggest something?
Thanks! Marco
