Power Integrations announced the addition of a 900V device to its InnoSwitch-EP family of off-line CV/CC flyback switcher ICs. The new device targets power supplies operating from high-voltage DC and three-phase power sources found in industrial, motor-drive, metering, and renewable energy applications, and standard mains-voltage applications where continuous operation during line swells and surges is required. The 900V InnoSwitch-EP ICs are efficient, typically 85% for a dual output 18W design, eliminating heat sinks and enabling highly compact power supply implementations. The new 900V InnoSwitch-EP ICs feature an uprated, integrated 900V power MOSFET which provides a significant operating margin for 450VAC industrial systems, increasing reliability, and operational life. Working continuously with an input voltage of up to 450VAC, an optional layer of protection, line UV/OV, prevents the IC from switching and protects the circuit up to 650VAC. 900V InnoSwitch-EP ICs enhance power-supply reliability by reducing BOM count to a minimum level and by eliminating optocouplers which degrade with time. Devices exceed all international energy-efficiency standards such as ENERGY STAR, California Energy Commission and European Union Code of Conduct (CoC), ErP Directive, and the US Department of Energy standards. Devices are UL1577 and TUV (EN60950) safety-approved and EN61000-4-8 (100 A/m) and EN61000-4-9 (1000 A/m) compliant.
