Description

When AC voltage is applied, CAPZero blocks current flow in the

X capacitor safety discharge resistors, reducing the power loss to

less than 5 mW, or essentially zero

voltage is disconnected, CAPZero automatically discharges the

X capacitor by connecting the series discharge resistors. This

operation allows total flexibility in the choice of the X capacitor to

optimize differential mode EMI filtering and reduce inductor costs,

with no change in power consumption.

Designing with CAPZero is simply a matter of selecting the

appropriate CAPZero device and external resistor values in Table 1

for the X capacitor value being used. This design choice will

provide a worst case RC time constant, when the AC supply is

disconnected, of less than 1 second as required by international

safety standards.

The simplicity and ruggedness of the two terminal CAPZero IC

makes it an ideal choice in systems designed to meet EuP Lot 6

requirements.

The CAPZero family has two voltage grades: 825 V and 1000 V.

The voltage rating required depends on surge requirement and

circuit configuration of the application. See Key Applications

Considerations section for details.

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

Self supplied – no external bias required

High common mode surge immunity – no external ground

connection

High differential surge withstand – 1000 V internal MOSFETs

<5 mW consumption at 230 VAC for all X capacitor values

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
