CAP004DG

™ CAPZero Family Zero1 Loss Automatic X Capacitor Discharge IC Product Highlights 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 R1 D1 MOV and Other EMI Filter Components AC X Capacitor CAPZero D2 R2 PI-6599-110711 EcoSmart ® – Energy Efficient <5 mW consumption at 230 VAC for all X capacitor values Applications All ACDC converters with X capacitors >100 nF Appliances requiring EuP Lot 6 compliance Adapters requiring ultra low no-load consumption All converters requiring very low standby power Figure 1.
