VND830LSP Application Field and Working Principle

VND830LSP belongs to PMIC (Power Management IC) and is classified as a Power Distribution Switches, Load Drivers.

VND830LSP is an IC specially designed for NoteBooks and Mobile phones, mostly applied to distribute power and workload of a system in different modes, optimizing the power consumption accordingly. It is also capable of switching from one operating mode to another in a very quick speed.

The power supply of VND830LSP consist of two sub-PDNs (Power Distribution Networks) and a single Over-current protection system. The two PDNs are designed according to different voltage levels; the high voltage PDN (h-PDN) provides power management to components such as processors, and the low voltage PDN (l-PDN) provide power management to those components requiring 3.3V or lower.

Besides power decision, the other main function is workload manage, that enables user to dictate the workload of each component. This can be programmed according to user functions, such as power up/down and suspend. The user also has the ability to monitor the power consumption of all components as well as be able to modify, reload and store settings for different modes of operation.

When it comes to the actual working principle, the components included in the actual VND830LSP IC can be divided into two parts: the core logic and the application logic.

The core logic is the power management unit of the IC, it is responsible for all power distribution related operations. This unit essentially controls the power on/off or the power budgets of the two PDNs, which in turn controls the power to different components (high-voltage and low-voltage) in the system. It is also responsible for the power sequencing, load balancing and power optimization.

The application logic, on the other hand, manages all system workload related operations. This includes monitoring the real-time power consumption of all components, and executing the programming settings for different modes of operation. It also provides system control features like freeze/sleep and smartcharge.

Overall, VND830LSP IC is an very effective power manager for mobile phones and notebooks. It is capable of switching from one operating mode to another in a very quick speed, thus optimizing the power consumption accordingly. It is also very reliable, highly configurable and can monitor the real-time power consumption of all components.
