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
