Abstract
A multi-phase dc-to-dc converter controlled by hysteretic PWM method is presented in this paper. An and-gated logic circuit is employed for the synchronization and its operating principle is described. A 5 V to 1.5 V prototype buck converter of two-phase is implemented for a POL power supply. From the experiments, it is confirmed that the proposed method can be well synchronized, and an excellent dynamic performance is archived for the large load current transients. In addition, improved power efficiency and a good current sharing characteristic is derived.
