Feature: System design
Electronic devices will be forced to spend more time in low-power modes. While operating in each mode, all necessary functions must be performed within a fixed power budget
power consumption limits and system behaviour will become mandatory from 9th of May, 2025.
Unique
technology delivers more from fixed power budgets

he global consumer electronics market is set to reach $1 trillion by 2030, driven by continued demand for new functionalities and technologies. The total number of Internet of Things devices will double to 30 billion during the same period, as manufacturers continue to
develop more advanced, high-performance and convenient products with integrated connectivity. While the number of connected devices continues to grow,
there are obvious implications for global energy consumption at a time when the world is focused on reducing CO2
emissions,
ensuring long-term sustainability and achieving net-zero targets. EU Commission regulation 2023/826 was published on April 17th 2023 to help address this challenge by introducing updated eco-design requirements for electrical equipment operating in standby, networked-standby and off modes. New
Latest regulations Eco-design requirements first introduced standby power limits in 2010, which have progressively tightened. The latest update recognises technological progress and expands the scope even further. Latest rules aim to deliver an additional 4TWh and 1.36Mt of CO2
savings. The following changes apply:
• From 2025, devices must not consume more than 0.5W in standby or off mode, or 0.8W if they are on standby while displaying their status or information.
• From 2027, devices must not consume more than 0.5W in standby, 0.3W in off mode, or 0.8W if they are on standby while displaying their status or information.
• From 2027, devices in networked standby must not consume more than 2-7W.
• When equipment is not providing a main function, it must automatically switch to a low-power mode in the shortest possible time appropriate for the intended use of the equipment.
• When not providing a main function, networked equipment must automatically switch to standby mode in the shortest possible time appropriate for the intended use of the equipment (20 minutes max.). Electronic devices will thus be forced to spend more time in
low power modes. Whilst operating in each mode, all necessary functions must be performed within a fixed power budget. Introducing more sophisticated features may increase the power requirements, making this task even more challenging.
Pulsiv Osmium technology to the rescue Conventional power supplies are notoriously inefficient during low-power modes, since they are usually designed for peak efficiency at maximum output. Reducing energy waste in the AC to DC conversion process will be essential to make more power available in standby modes. Pulsiv Osmium technology offers a new method of AC to DC
power conversion that reduces losses and increases the total available power, particularly under low-load conditions.
