【Abstract】 PSM (pulse skip modulation) is a novel and excellent modulation mode for DC/DC converters. The basic structure of PSM and charge pump are described, as well as the principle of the PSM-based charge pump, which has the advantages of fast response, excellent anti-perturbation, robust load regulation, weak EMI and high efficiency. Finally, the electrical performance of the device is discussed.更多还原
