Safety-rated switcher ICs operate through line surges and swells
SAN JOSE, Calif.--(BUSINESS WIRE)--
Power Integrations (Nasdaq: POWI),
the leader in high-voltage integrated circuits for energy-efficient
power conversion, today announced the addition of a 900 V device to its InnoSwitch™-EP
family of off-line CV/CC flyback switcher ICs. The new device targets
power supplies operating from high-voltage DC and three-phase power
sources found in industrial, motor-drive, metering and renewable energy
applications, and standard mains-voltage applications where continuous
operation during line swells and surges is required. The 900
V InnoSwitch-EP ICs are highly efficient – typically 85% for a dual
output 18 W design – eliminating heat sinks and enabling highly compact
power supply implementations.

Explains David Chen, director of applications engineering at Power
Integrations: “Designers of high-voltage systems often have megawatts of
power at their disposal, from which they may need to draw off a few
milliwatts to feed a low-voltage microprocessor system, or a few tens of
watts for inverter gate drivers. The new 900
V InnoSwitch-EP devices drastically simplify the design of robust
highly reliable power supplies operating from commonly available
industrial voltages.”
Launched last year, Power Integrations’ InnoSwitch-EP IC family employs
the company’s innovative, safety-rated FluxLink™
magneto-inductive coupling technology and includes synchronous
rectification with accurate secondary-side regulation, resulting in
highly efficient, reliable power supply circuits that do not need an
optocoupler. The new 900
V InnoSwitch-EP ICs feature an uprated, integrated 900 V power
MOSFET which provides a significant operating margin for 450 VAC
industrial systems, increasing reliability and operational life. Working
continuously with an input voltage of up to 450 VAC, an optional layer
of protection – line UV/OV – prevents the IC from switching and protects
the circuit up to 650 VAC. This flexibility is a huge benefit for
designers of power supplies that suit all worldwide conditions.
900
V InnoSwitch-EP ICs enhance power-supply reliability by reducing BOM
count to a minimum level and by eliminating optocouplers which degrade
with time. Devices exceed all international energy-efficiency standards
such as ENERGY STAR®, California Energy Commission and European Union
Code of Conduct (CoC), ErP Directive, and the US Department of Energy
standards. Devices are UL1577 and TUV (EN60950) safety-approved and
EN61000-4-8 (100 A/m) and EN61000-4-9 (1000 A/m) compliant.
900
V InnoSwitch-EP samples are available now. Devices are priced at
$0.95 in 10,000-piece quantities. Reference design, DER-531, is
available from the Power Integrations website at www.power.com/innoswitch-ep.
