Optimized efficiency and standby power performance

Power Integrations announced its InnoSwitch-CE ICs, a new class of its InnoSwitch family of off-line CV/CC flyback switcher ICs. The devices are optimized for consumer electronics applications where government regulations for Total Energy Consumption (TEC) are of utmost importance. InnoSwitch ICs use a magneto-inductive coupling technique called FluxLink, which enables precise switching control of both primary and secondary MOSFETs without unreliable optocouplers. This topology provides efficient synchronous rectification without the risk of shoot-through during transient loads or line surges, enhancing product reliability. The technique also exhibits cross-regulation performance, which often permits the elimination of DC-DC converter stages in multi-output designs, further enhancing power sub-system efficiency and reducing system cost. InnoSwitch-CE ICs target adapters and chargers for smart mobile products as well as open-frame power supplies for set-top boxes, computer monitors, and other consumer audio-visual and entertainment products. InnoSwitch-CE ICs consume less than 10 mW no-load and are also efficient across the entire load range, minimizing the energy wasted in low-power standby or sleep modes. InnoSwitch-CE ICs include an on-chip 650V MOSFET with accurate line OV/UV monitoring, which delivers protection against line surges and swells. Devices support multiple outputs with an accurate external current sense. InnoSwitch-CE devices exceed all international energy-efficiency standards such as ENERGY STAR, California Energy Commission, European Union Code of Conduct (CoC) Version 5, Tier 2, and the US Department of Energy standards (DoE 6). Devices are UL1577 and TUV (EN60950) safety-approved, and EN61000-4-8 (100 A/m) and EN61000-4-9 (1000 A/m) compliant.
