To participate you need to register. How would I know the peak current which this is designed.? Plus, you always have to use the worst case values. Your name or email address: I don’t have the formula for the cap on me. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at So you need to change R1 to change the 10v output.

They are designed for that chip alone, not a generic buck converter. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.
