Summary and Features

• Highly integrated IC realizes a significant reduction in component count

• Main transformer resets with a 700 V MOSFET and no reset winding

• Input power < 1 W (with standby loaded to 0.5 W and the main supply off)

• Meets Blue Angel 5 W requirement (measures 4.1 W, at specified conditions)

• Passes EN55022 B conducted EMI limits, with more than 10 dB of margin

• Simple voltage mode control provides good transient response & regulation

The products and applications illustrated herein (including circuits external to the products and transformer

construction) may be covered by one or more U.S. and foreign patents or potentially by pending U.S. and

foreign patent applications assigned to Power Integrations. A complete list of Power Integrations’ patents
