Hello All,
I wish to use the dsPIC30F4011 in my application.
There are two regulators I have to use in my application. The one is from TI LM25117-Q1, which is Step-down regulator . The dsPIC is a 40 PIN digital signal controller. I am confused about using digital POT , optocoupler, or anything other circuit components to control the output voltage of LM25117-Q1. It has a FB pin, is it feasible to use any op-amp with few components to control and change the output voltage. ?
Using PWM Technique, is also a possible way for controlling the output voltage.
Attached is the diagram of LM25117-Q1 (typical schematic)
and dsPIC30F4011.
Suggestions, changes , any ideas welcome!
