PMBus Insights

What is PMBus?

PMBus (Power Management Bus) is an open standard power-management protocol that facilitates communication between power converters and other system devices. It is commonly used to monitor and control power supplies, enabling features like remote voltage adjustment, current limiting, and temperature monitoring. PMBus is often implemented over the SMBus (System Management Bus) serial interface.
