Revision
Low cost (low component count with single sided printed circuit board)
Low conducted EMI: meets CISPR22B/EN55022B without requiring a Y capacitor
Meets EN/UL 1000-4-5 CLASS 4 (4 kV), using line overvoltage protection feature
Designed to IEC60950 safety standard requirements
Ultra-low earth leakage current (<1 µA @ 265 VAC, 50/60 Hz) eliminates line frequency audio
hum in voice applications (“ground loops”)
Compact Design (L = 113 mm, W = 39 mm, H = 25 mm)
High efficiency (≥70% at 85 VAC)
Line undervoltage shutdown prevents turn-off output glitches
Line overvoltage shutdown provides extended line swell protection
Hysteretic thermal shutdown provides automatic supply recovery after fault removal

... Although the EP-18 is designed to satisfy safety isolation requirements, the engineering prototype has not been agency approved. Therefore, all testing should be performed using an isolation transformer to provide the AC input to the prototype board. Power Integrations, Inc.

... The “P” and “G” packages allow either line sensing or external current limit programming through the M pin. “Y” and “R” packages allow both functions via the L and X pins. Reducing the current limit in this design would allow a smaller transformer to be used, if desired. Power Integrations, Inc. Tel: +1 408 414 9200 Fax: +1 408 414 9201 www.powerint.com ...
