I have a buck converter that I am working on. Based on the inductor size that I use, the switching freq and input vs output voltage, I need about 200ma to get the buck converter into continuous mode. My app only uses about 100ma, so I am looking for ideas on how to soak up aleast another 100ma to get me into continuous mode.
My app is not battery powered. The case for the project is a transparent blue, so no crazy bight LEDs.
I am looking for a way that:
-generates minimum heat
-low component count
-cheap to implement
-minimal board space required
I am currently getting about a 100mv pk-pk ripple on my output. I am hoping to get this much lower by getting into the continuous mode. Maybe putting an LC filter on the output is a better idea.
