Switcher ICs Optimized for Efficiency and Standby Power Performance

Power Integrations announced its InnoSwitch-CE ICs, a new clade of its InnoSwitch family of off-line CV/CC flyback switcher ICs. The new 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. This topology provides highly efficient synchronous rectification without the risk of shoot-through during transient loads or line surges, enhancing product reliability. The technique also exhibits 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.
