Prelude Power Management
There are as many Power Management Networks (PMN) as there are applications. Making the right choices for embedding PMNs into System-on-Chips (SoC) might result in headaches for the integrator.
Taking this into account, Dolphin Integration has developed its own two-pronged approach to architecturing PMNs viewed as a flow of energy from the source to the load in a SoC: a custom upstream offering combined with a standard downstream offering. These provide integrators with building blocks required to construct a large portion of any PMN. The main objective is to optimize each element of the PMN (Linear and Switching Regulators, switches, Battery Chargers etc.) to meet the particular needs of the PMN floors: efficiency, low power, low BoM, etc.

 Upstream: Concerns all the custom features (internal or external to the SoC) directly linked to the power source(s).
Interface of Prairies: the IdP is defined by a limited voltage range and a maximum noise spectrum that can be tolerated on the IdP by the downstream regulators and loads. It is a standard that ease selection and integration of upstream and downstream functions.
Downstream: Concerns all the standard features directly linked to consuming elements (loads) of the SoC.
Key Benefits
-
Power efficiency optimization of the entire PMN, not only of individual functions.
-
Application specific: upstream solutions are developed as custom products to fit each SoC applications.
-
Improved Return-on-Investment: downstream offering is based on Virtual Component (ViC) perfectly fitting the supply needs of SoC loads.
-
Low BoM thanks to inductorless and capless application schematics.
-
Easier Integration limiting the ViC noise disturbances thanks to a robust architecture.
JAXpower modularity
In order to provide integrators with the appropriate regulators for their system needs, while insuring a fast delivery, the blocks of Dolphin’s regulators are ready made. Integrators can express their needs and Dolphin will be able to offer the optimized solution for the loads or the IdP
