Industrial and Three-Phase Power Supply Applications with New 900 V InnoSwitch-EP ICs

Power Integrations announced the addition of a 900 V 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 900 V InnoSwitch-EP ICs are highly efficient – typically 85% for a dual output 18 W design – eliminating heat sinks and enabling highly compact power supply implementations.

The 900 V InnoSwitch-EP ICs feature an uprated, integrated 900 V power MOSFET which provides a significant operating margin for 450 VAC industrial systems, increasing reliability and operational life. Working continuously with an input voltage of up to 450 VAC, an optional layer of protection - line UV/OV – prevents the IC from switching and protects the circuit up to 650 VAC. This flexibility is a huge benefit for designers of power supplies that suit all worldwide conditions.
