InnoSwitch-CE switching power supply IC related technical indicators

Integrations Corporation releases InnoSwitch™-CE IC. The new device is a sub-series of the InnoSwitch series of constant voltage/constant current offline flyback switch ICs. InnoSwitch-CE IC is suitable for consumer electronics applications related to TEC regulations (TEC regulations are important total energy consumption regulations recognized by the government).

InnoSwitch IC uses magnetic coupling technology called FluxLink™, invented by Power Integrations, which allows precise switching control of primary and secondary MOSFETs simultaneously without the need for unreliable optocouplers. This topology provides efficient synchronous rectification without the risk of breakdown due to simultaneous conduction of the primary and secondary switches during dynamic loads or input surges, thereby improving product reliability. The technology also offers excellent cross-regulation, often eliminating the need for DC-DC converter circuitry in multiple-output designs, further improving power subsystem efficiency and reducing system cost.

InnoSwitch-CE ICs can be used in adapters and chargers for smart mobile products as well as open power supply applications in set-top boxes, computer monitors and other consumer audio and video products and entertainment products. InnoSwitch-CE ICs consume less than 10 mW of no-load power and are also extremely efficient over the entire power range, reducing energy consumption in low standby or sleep modes, which is often necessary to meet challenging TEC regulations. It's important.

InnoSwitch-CE IC integrates a 650 V MOSFET with accurate input overvoltage/undervoltage monitoring to provide excellent input surge and voltage swell protection. The new device supports multiple output applications and has accurate external current sensing capabilities.

Shyam Dujari, director of product marketing at Power Integrations, said: “Consumer electronics products need to be small in size and consume very low power. Importantly, most of these products, such as set-top boxes and monitors, remain plugged into an electrical outlet when not in use. Because InnoSwitch-CE ICs integrate synchronous rectification drive circuitry and offer high efficiency over the entire load range, including standby and idle modes, they are an important new option for designers facing challenging TEC requirements."

Power supply designs using InnoSwitch-CE can exceed the energy efficiency requirements of all international energy efficiency standards, such as ENERGY STAR®, California Energy Commission standards, European Union Code of Conduct (CoC) 5th Edition Tier 2 standards, and U.S. Department of Energy standards (DoE 6). They are UL1577 and TUV (EN60950) safety certified and comply with EN61000-4-8 (100 A/m) and EN61000-4-9 (1000 A/m) standards.
