Targeting 480 VAC industrial applications and appliance power supplies
for regions with unstable mains voltage

SAN JOSE, Calif.–(BUSINESS WIRE)–lt;a href=”https://twitter.com/hashtag/PowerIntegrations?src=hash” target=”_blank”gt;#PowerIntegrationslt;/agt;–Power Integrations (Nasdaq: POWI),
the leader in high-voltage integrated circuits for energy-efficient
power conversion, today announced the release of a suite of offline
switcher ICs incorporating 900 V primary MOSFETs. The newly released
devices include ICs for high-efficiency isolated flyback power supplies
and for simple non-isolated buck converters. Applications include
three-phase industrial power supplies up to 480 VAC, and high-quality
consumer products destined for regions with unstable mains grids,
tropical regions with frequent lightning strikes or any area where
high-energy ring-waves and surges are prevalent.

The new products include 900 V versions of the LinkSwitch-TN2
ICs for simple, non-isolated buck converters plus three new members of
the flagship InnoSwitch3-EP
IC family, which enable extremely high-efficiency isolated flybacks up
to 35 W. All members of the 900 V product families feature internal
control engines optimized for high efficiency across load, enabling
designs to easily meet energy-related products (ErP) limits, and a
variety of line and load protection mechanisms to further enhance system
robustness and reliability.

The 900
V LinkSwitch-TN2 ICs deliver the lowest-component-count switcher
solutions for buck converters. Devices feature selectable current limit
and fully integrated auto-restart for short-circuit and open-loop
protection. The use of frequency jittering greatly reduces EMI, and
devices easily meet high-voltage creepage and clearance requirements
between DRAIN and all other pins both on the PCB and at the package.

The 900
V InnoSwitch3-EP flyback switcher ICs provide lossless line OVP
sensing, which automatically interrupts switching when line voltages
exceed a selected threshold, preventing damage to the power supply
during severe line overvoltage situations. Devices achieve
industry-leading efficiencies of up to 90% across line and load
conditions, reducing power supply losses and resulting in compact power
supplies up to 35 W without heatsinks. The 900 V InnoSwitch3-EP ICs
employ Power Integrations’ innovative isolated digital communications
technology, FluxLink, plus synchronous rectification (SR), QR switching
and a precise secondary-side feedback sensing and control circuit. This
results in highly efficient, accurate, reliable power supply circuits
without the need for unreliable optocouplers.

Comments senior product marketing manager Silvestro Fimiani: “These
switching power ICs enable designers of three-phase utility meters,
motors, industrial auxiliary power supplies, appliances and even
cellphone chargers to realize a truly ‘one-world’ power supply that
meets the reliability expectations of users everywhere. For example,
OEMs addressing the burgeoning market in India for high-quality consumer
products suffer a continuous stream of electrically damaged and returned
products that must be serviced or replaced. Our 900 V switcher ICs
provide effective and inexpensive protection and a substantial reduction
in operating and product-support costs.”

Samples of the 900 V InnoSwitch3-EP ICs are available now, priced at
$1.18 for 10,000-piece quantities. Samples of 900 V LinkSwitch-TN2 ICs
are also available priced at $0.60 for 10,000-pieces orders. Technical
support for the 900 V family of ICs is available from the Power
Integrations website at: https://ac-dc.power.com/applications/unstable-mains-voltage.
