Inductor ripple buck
WebWhen converter output ripple voltage must be less than ≈2% of output voltage, it is usually better to add an output filter (Figure 22) than to simply “brute force” the ripple by using … WebFor a buck converter, these low dropout operation conditions require high duty cycle operation that may approach 100%. However, when operating near 100% duty cycle with light loads, the Bootstrap capacitor can be discharged below the BOOT UVLO threshold, causing high ripple voltage on the output side.

WebLED lighting has become a mature technology with stringent requirements on light quality. In order to achieve high light quality, there is a strong trend towards two-stage topologies. These two-stage topologies ensure that the light flicker or also called light ripple remains at low levels according to IEEE1789 and other new upcoming regulations.
