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
