I am relatively new to electronics and trying to design a buck converter circuit using the XL1509-ADJE1. The datasheet specifies that for the adjustable versions (which this is) you should use specific capacitor values depending on the output voltage you desire. The only issue is, I need 3.3v out and the datasheet only gives capacitor values for 2v and 4v (and upwards). What value should I use?
Another weird thing I wanted to know (just out of interest) is why the datasheet gives different capacitance values depending on the type/brand of the capacitor. I have included the table from the datasheet and as you can see it shows different values for electrolytic and tantalum capacitors. Thanks! :)
