It supports up to 15 power phases with individual load monitoring and dynamic load balance, and can be configured according to the specific power requirements.

Working Principle: LX8384-15IP utilizes a Digital Power Manager (DCPM) as an integral power controller. The DCPM has two main components – the Power Factor Correction (PFC) stage and the primary controller. The PFC stage is responsible for stabilizing the power supply, while the primary controller directs the overall power supply processes.

The DCPM works by calculating the actual current demand of the processor and then matching it with the appropriate voltage levels to ensure a continuous and steady supply of power. The primary controller also ensures that the output voltage matches the input voltage and remains within the expected range for safe, efficient operation.

In addition, the DCPM performs several power management tasks such as phase current monitoring, VOUT settings, phase sequencing, and over-current protection. It also monitors and controls the overall temperature of the system. This helps to ensure that the system runs at an optimal temperature for maximum efficiency.

Overall, LX8384-15IP is a multi-phase digital Power Management IC with high efficiency, small form factor, and advanced thermal control and power management features. It is ideal for low-power applications, especially those requiring high-precision output, low noise, and low heat dissipation.
