Flyback switcher ICs optimize efficiency and standby power performance
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, invented by Power Integrations, which enables precise switching control of both primary and secondary MOSFETs without unreliable optocouplers. The topology provides efficient synchronous rectification without the risk of shoot-through during transient loads or line surges, enhancing product reliability. The technique also claims to exhibit excellent 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 very efficient across the entire load range, minimizing the energy wasted in low-power standby or sleep modes, which is often critical to meeting challenging TEC regulations.
InnoSwitch-CE ICs include an on-chip 650 V MOSFET with accurate line OV/UV monitoring, which delivers excellent protection against line surges and swells. Devices support multiple outputs with an accurate external current sense.
InnoSwitch-CE devices claim to 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.
Six devices are available, delivering between 12 W and 25 W of output power for USB Type-C chargers and consumer electronics such as set-top boxes. InnoSwitch-CE samples are available now. Devices are priced from $0.80 in 10,000-piece quantities.
