- Abstract
- Recently, when the buck converter has a light load,it uses the Pulse Frequency Modulation (PFM)operation for high efficiency. In this case, most circuits in buck converter are off while it uses thePFM operation. Accordingly, when the buckconverter wakes from PFM operation, output voltage tends to drop significantly to the delayed time for steady state. This problem must be solved because it affects other analog or digital systems. Therefore new compensation circuit using the additional amplifier which has a low power is proposed in this paper
