Find out how to get the most from your SoC design for meeting multiple power needs.
In today's convergence world, the complexity of the system demands a lot from the supply and management of power. The world of a single high-power lossy regulator for supplying power to the whole system is long gone by. A typical portable system has a multiplicity of regulators " both in type and in numbers. As System-on-Chips (SoC) provide more to the system in terms of the level of integration, performance and battery-life to the system, integration of power-management into the SoC becomes a natural "low-hanging fruit" to offer to the system-integrators of today.
First, let us take a quick look at what actually necessitates such complex power-regulator requirements. For this, it would be instructive to explore the insides of a cell-phone or any other portable gadget. The following figure shows the functions that a high-end portable gadget would integrate.
