Programming precise power-sequencing delays and slew rates has become a routine requirement for power supply designers who need to power today’s sophisticated multi-core logic and mixed-signal devices. Until recently, the power control and management circuitry necessary to achieve these tasks was often as complex as the underlying DC/DC converter topologies, complicating circuit layout, consuming extra power, and often compromising performance. As well, optimizing power system’s performances at any point of operation is a must that nobody can ignore. With its 3E power solution, Ericsson becomes the first company to offer a complete range of board-mounted-products based on digital control and monitoring, and in doing so, contributes to reduce energy consumption, and CO2 emissions.
