In this paper a novel method for fast transient low power and high dropout DC-DC converter for embedded applications has been proposed. Fast transient is achieved by introducing one fast current control feedback loop with relatively slow current control feedback loop with a small Miller capacitor. Inner feedback loop is made faster by utilizing proposed push-pull structure of linear regulator. To...
An architecture of inductor-less DC-DC boost converter for high efficiency and low output ripple is proposed. Output ripple is reduced by splitting flying capacitors into a number of smaller elements and using a new switching scheme called non-overlapped rotational-interleaving (NORI). The proposed switching scheme also helps to eliminate reversion and shoot through current hence improves the power...
This paper deals with the efficiency improvement of an embedded hybrid DC-DC converter which is suitable for high dropout embedded regulation. In the proposed topology, power efficiency is improved by eliminating shoot-through current of switched-Capacitor module using Non-overlapped Rotational Time Interleaving (NRTI) switching scheme. In addition to the improvement in power efficiency, this scheme...
