The Power Management Bus (PMBus®) is an open standard digital power-management protocol: simple, robust, and extensible. About 40 PMBus member companies adopt, promote, and improve the standard. Benefits are efficiency, interoperability, reduced design complexity, and shorter time-to-market for...
PMBus(Power Management Bus)是一种电源管理总线一种控制电源转换器的开放的标准协议。它脱胎于基于I2C和SMBUS(System Management Bus),但是定义了很多和电源管理相关的命令。可以说是之前的I2C是物理层(具体Slave会有指令集,但只是怎么该slave,没有统一的指令集),而现在的PMbus却有了协议层,如果想用PMbus就必须遵...
The PMBUS power supply structure capable of achieving general use comprises a power supply body, a data detection processing module and a system management bus (SMBUS) port, wherein the data detection processing module and the SMBUS port are integrated on the power supply body and connected ...
VRM电源已采用了数字化方案,其内部控制电路的PMBUS(Power Management BUS:电源管理总线)相互连接,并可在服务器的BMC中对VRM电源进行统一的管理,比如在服务器测试阶段实现对VRM电源的全面监测,确保测试更全面、更完整;在服务器上线运行时,对VRM电源的内部寄存器进行轮询,可长期有效的实时监控VRM电源的电压、电流信息。...

电源管理总线(PMBus)参考设计是一种开放标准协议,被定义为与电源转换和其他设备进行通信的一种方式。作为基于SMBU协议的行业标准串行通信接口,它被视为系统管理总线的扩展,并支持许多新功能。像SMBus一样,PMBUs协议定义了三层,即物理层,数据链路层和网络层。此设计包含WISHBONE接口,并着重于数据链路层协议的实现。将...
The PMU consists of internal DC-DC converters, PMU registers, etc., and provides power supply for the SOC's processor, PLL, DDR, image unit, etc. At the same time, the PMU also controls the external power supply system through the Power Management Bus (PMBus). ...
NXP’s Power Management Bus (PMBus) is an open standard power-management protocol with fully defined commands that support communication with power converters and other digital power-management devices and host processors in ...
为了确保外部MOSFET保持在安全工作区内,热插拔控制器在较高VDS电压下调节电流限制。该设备还包括各种遥测,可监控运行状况。只要电源轨达到稳压状态,电源就绪(PG)信号就会打开,并且某些热插拔控制器包含PMBus监视,该监视允许对设备状态进行实时反馈。 由于热插拔控制器通过控制外部RSNS和MOSFET进行操作,因此它们不包含固有电...
Using PMBus™ for Improved System-Level Power Management Kurt Hesse Abstract This topic provides a brief high-level introduction to the PMBus Standard for controlling a power supply using an enhanced serial interface, and then describes the more common and basic PMBus commands. Several system ...
