A reference design for LED streetlights, high-bay lights and other high power LED lighting applications has been announced by Power Integrations. RDR-382 describes a constant current, 43V (nominal), 150W reference power supply for 90-265VAC solid-state lighting, utilising the company's HiperPFS-2 PFC controller ICs and HiperLCS integrated LLC power stage ICs.

By integrating primary and secondary feedback circuits, the InnoSwitch IC family is set to revolutionise switch-mode power supply design, says Power Integrations. The ICs use FluxLink safety-isolated communication technology, which combines primary - and secondary-switcher circuitry to reduce component count.

  Power Integrations has revealed that the CAPZero two-terminal, automatic X-capacitor discharge ICs have been certified to meet the IEC 62368. Replacing IEC 60950 and IEC 60065, the IEC 62368 safety standard covering TVs and IT equipment will soon become mandatory.

A series of switching ICs suitable for mobile devices which are subject to 30mW no-load limitations, has been released by Power Integrations. The LinkSwitch-3 series delivers primary-side regulation for chargers and adapters up to 10W, making them suitable for smartphones and tablets which are subject to upcoming mandatory US DoE EPS efficiency regulations and EU CoC Tier 2 guidelines.

Power Integrations has announced that a Federal District Court in Delaware has granted its request for another permanent injunction against Fairchild Semiconductor. The ruling follows a 2012 jury verdict in which approximately 80 Fairchild products were found to violate three of Power Integrations’ patents.

PCIM 2014: With a high, universal input range to suit consumer and enterprise use around the globe, the LYTSwitch-2 LED driver IC from Power Integrations is based around a monolithic silicon transistor, operating at 725V. The IC delivers up to 12W of controlled output power and reduces component count to just 23, for smaller, more reliable LED lighting design.  

Based on a member of Power Integrations’ LinkZero-LP family of ICs, the DER-417 reference design has been announced by Power Integrations. This reference design is for an 8W, universal-input auxiliary power supply that achieves zero standby power consumption for appliance applications.

Power Integrations has announced a verdict in one of its ongoing patent infringement lawsuits against Fairchild Semiconductor. After a month-long trial in federal district court in San Francisco, a jury found that Fairchild willfully infringed two of Power Integrations’ patents, and awarded Power Integrations damages of $105 million.

Power Integrations introduce a new family of power ICs, which combine two-switch-forward and flyback power-supply controller ICs with integrated high-voltage MOSFETs. Enabling a smaller form factor and higher power density, the high level of integration on the HiperTFS-2 family reduces the component count by more than 20.

Power Integrations' new CAPZero automatic X-capacitor discharge IC has been certified to meet IEC CTL DSH 1080. This is the new mandatory addition to the Certification Body scheme of the IEC60950 and IEC60065 standards governing X-capacitor discharge safety regulations. Simple SO-8-packaged two-terminal devices, the CAPZero ICs only require discharge resistors to automatically implement the X-capacitor discharge function.

Power Integrations has today revealed an industry first with its reference design for a Qualcomm Quick Charge 2.0-enabled charger power supply. Launched by Qualcomm earlier in 2013, the Quick Charge 2.0 protocol up to 75% faster charging of mobile devices than conventional USB charging technology.

Power Integrations annonce ce jour une conception de référence de lampe PAR38 à gradation, développée en collaboration avec Cree, Inc. Le nouveau design de référence, décrit dans le document DER-350, utilise la nouvelle puce LYT4317E de la famille LYTSwitchTM-4 de commandes à un étage de Power Integrations, associée aux LED MT-G2 de la famille EasyWhite de Cree.

Power Integrations today announced a reference design for a dimmable PAR38 spotlight, developed in collaboration with Cree, Inc.  The new reference design, described in DER-350, uses Power Integrations’ new LYT4317E, a member of the company’s LYTSwitchTM-4 family of single-stage drivers, along with Cree’s MT-G2 EasyWhite LEDs.

Power Integrations have introduced the CHY100, the first AC-DC wall-charger interface IC that enables designers of mobile devices to implement the Quick Charge 2.0 protocol from Qualcomm. Launched earlier this year, Quick Charge 2.0 enables users to charge mobile devices up to 75% faster than when using conventional technology. Used in combination with Power Integrations’ AC-DC switcher ICs, the CHY100 incorporates all the necessary elements re...

Power Integrations is driving down the cost of LED drivers with the launch of its LYTSwitch-0 ICs. The ICs target cost-sensitive, non-isolated, non-dimmable GU10 bulbs and other space-constrained bulb applications. Using a 6V high-side buck converter as an example PI says savings are made at each step of the design.

Power Integrations today introduced its LYTSwitch-0 ICs, a new series of devices within the LYTSwitch family, offering a unique combination of simplicity, reliability and efficiency. LYTSwitch-0 ICs are ideal for cost-sensitive, non-isolated, non-dimmable GU10 bulbs and other space-constrained bulb applications.

CT-Concept Technologie has launched a new dual-channel IGBT-driver core which can handle voltages of up to 4.5 kV. Featuring transformer-based signal isolation - rather than more expensive fibre-optic technology - and an on-board power supply, the new 2SC0635T units are cost-effective, compact and reliable.

Power Integrations today introduced HiperPFS-2, a new family of high-efficiency, active-PFC ICs for offline applications from 100 W to 380 W. HiperPFS-2 ICs combine a boost PFC controller, driver, PFC MOSFET, PFC diode and protection circuits in one package, enabling exceptionally compact designs ideal for small-form-factor power supplies as used in mini-tower PCs, all-in-one PCs, game console adapters and TVs.

Power Integrations introduce the LQA200 series of 200 V diodes. The company’s Qspeed high-performance silicon diodes are based on merged-PIN technology that offers ‘soft’ switching and low reverse recovery charge. This unique balance of features enables high-frequency operation and permits the use of small, inexpensive magnetic components while maximizing operational efficiency.
