CAPZeroFamily
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
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
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 zero1 at 230 VAC. When AC
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.
