Power Integrations (Nasdaq:POWI),
the leader in high-voltage integrated circuits for energy-efficient
power conversion, today announced CAPZero™-2
ICs, the next generation of its CAPZero
line of innovative, two-terminal, X capacitor discharge ICs. CAPZero-2
ICs increase design flexibility by covering a wide range of applications
and output power. Featuring an expanded X capacitor range from 0.1 µF to
6 µF, a rating of 1 kV breakdown voltage which allows for a
transient voltage capability of 6 kV, CAPZero-2 ICs
withstand severe line surges and swells.

CAPZero-2 ICs
are smart, high-voltage switches that significantly reduce no-load and
standby input power consumption. Placed in series with resistors that
provide a safe discharge path for a power supply’s X capacitor, CAPZero-2 devices
block current flow to the discharge resistors when AC voltage is
applied, cutting the power wasted in these components to zero. When the
AC voltage is disconnected, the CAPZero-2 switch
automatically and safely discharges the X capacitor by closing the
circuit and directing the energy away from the exposed AC plug.
Comments Edward Ong, product marketing manager at Power Integrations:
“With the introduction of our new CAPZero-2
ICs, power supply designers only need to qualify one part number for all
their X capacitor discharge IC applications. This increases design
flexibility and speeds time-to-market while reducing the resources
required to qualify devices.”
CAPZero-2 X
capacitor discharge ICs eliminate a key source of power losses while
allowing power supplies to comply with IEC
62368-1, the new over-arching safety
standard covering a broad segment of energy-using equipment. The new
standard replaces IEC 60950 and IEC 60065, and will shortly become
mandatory. Because CAPZero-2
devices are safety-certified to CB and Nemko requirements, developers do
not need to perform a separate capacitive discharge safety test of the
power circuit.
Applications include air-conditioners, home appliances, small
appliances, cookers, vacuum cleaners, TVs, desktop and notebook PCs,
projectors, workstations, computer monitors, and printers. Parts are
immediately available in SO-8 packaging priced at $0.19 each in
10,000-piece quantities. Product datasheet, design ideas, and
introductory video are available now on the Power Integrations website
