A 0.46 mm2 On-Chip Compensated Type-III Buck Converter Using an Inner Feedback Loop With a Seamless CCM/DCM Transition Technique

摘要

By simply adding a few components to a previous type-II voltage compensator, a single path inner feedback loop type-III voltage compensator is proposed. With the proposed compensator, a dc & x2013;dc converter achieves over & x002F; undershoot of 165 & x002F;220 & x00A0;mV and 1 & x0025; settling time of 8.5 & x002F;8 & x00A0;& x03BC;s when load current changes between 20
