Non-isolated DC/DC (Point-of-Load) with PMBus

TI has a broad portfolio of Power Management Bus (PMBus) Point-of-Load (PoL) DC/DC buck converters and controllers that meet your specific design requirements and our devices facilitate Active Power Management. PMBus is an I2C-based communication standard for power supply management that enables programming, configuring, sequencing, Adaptive Voltage Scaling (AVS) and margining of the power supply, with the optional capability of Telemetry - monitoring key parameters, such as input/output voltage, input/output current, input/output power, and internal or external temperature.

Hot swap

Hot swap controllers from TI offer FET protection by reducing the current limit at higher VDS to ensure that the MOSFET stays within its safe operating area (SOA). This second layer of protection makes the Hot swap solution more robust.
