Telecom power supply systems form the backbone of modern telecommunications. Without them, communication services would falter during power outages or fluctuations. Power factor corrected (PFC) AC/DC power supplies with load sharing and redundancy (N+1) at the front-end feed dense, high efficiency DC/DC modules and point-of-load converters on the back-end. This article focuses on the Analog Devices MAX15258, which is designed to accommodate up to two MOSFET drivers and four external MOSFETs in single-phase or dual-phase boost/inverting-buck-boost. Power supplies for information and communication devices are important devices for providing stable power supply 24 hours a day, 365 days a year for the various communication devices used to provide data communication services, such as telephone and Internet. Compared with. A communication power supply refers to a power supply equipped with digital communication interfaces, enabling remote control and monitoring, and is widely used in modern communication devices.
