Product Highlights
• Provides lossless ZC (Zero Crossing) signal to system MCU
• Meets IEC 60335 X capacitor discharge of <34 V in <1 sec
• One part to cover X capacitor values up to 6 mF
• Blocks current through X capacitor discharge resistors when AC
voltage is connected
• Automatically discharges X capacitors through discharge resistors
when AC is disconnected
• Simplifies EMI filter design – larger X capacitor allows smaller
inductive components with no change in consumption
• Only two terminals – meets safety standards for use before or after
system input fuse
• >4 mm creepage on package and PCB
• Self supplied – no external bias required
• High common mode surge immunity – no external ground connection
• High differential surge withstand – 1000 V internal MOSFETs
• NEMKO and CB certification
EcoSmart™– Energy Efficient
• <5 mW consumption at 230 VAC for all X capacitor values
Applications
• All AC-DC converters with X capacitors of 100 nF up to 6 mF
• Appliances requiring ErP Lot 6 compliance
• Adapters requiring ultra low no-load consumption
• All converters requiring very low standby power
• Lossless generation of zero crossing signal
