Power Integrations has introduced the 1SP0350V SCALE-2 single-channel +15/-10 V plug-and-play gate driver. Optimally suited to high-reliability applications in the HVDC and railway industries, the 1SP0350 gate driver reliably and safely drives 4500V Press-Pack IGBTs and IEGTs as well as other IGBT and IEGT form factors.

Going back a few years, the global LED market was hugely fragmented, with literally thousands of players. For example, approximately two years ago the biggest player in the world had around two percent of the market.

Employing a novel driver algorithm ensures high PF and low THD while maintaining very high efficiency, Power Integrations has announced an LED driver IC family. The LYTSwitch-1 single-stage, non-isolated, buck topology drivers enable the design of LED bulbs and tubes with high constant-current accuracy while using a minimum number of components.

  A joint development at Power Integrations has resulted in the Scale-iDriver ICs, using FluxLink from the low voltage team and the high voltage team’s expertise in soft shutdown.

  Optimised for consumer electronics applications where government regulations for Total Energy Consumption (TEC) are of utmost importance, Power Integrations has extended its InnoSwitch family with InnoSwitch-CE switcher ICs.

Power Integrations has expanded its InnoSwitch-EP family of off-line CV/CC flyback switcher ICs with the introduction of a 900V device. The 900V InnoSwitch-EP IC targets power supplies operating from high-voltage DC and three-phase power sources found in industrial, motor-drive, metering and renewable energy applications, as well as standard mains-voltage applications where continuous operation is required during line swells and surges.

The LYTSwitch-3 family has been added to the LYTSwitch line of LED driver ICs from Power Integrations. Well suited for bulbs, tubes and downlights up to 20W, LYTSwitch-3 ICs offer dimming performance with both leading edge and trailing edge TRIAC dimmers, and support both isolated and non-isolated topologies.

Power Integrations, in association with Cypress Semiconductor, announced a joint reference design describing a 20-watt, USB-PD compliant AC-DC power converter targeted at chargers for smart mobile devices. The design, titled DER-533, pairs the EZ-PD CCG2 USB Type-C port controller from Cypress with Power Integrations’ InnoSwitch -CP off-line CV/CC flyback switcher IC, enabling designers to produce a standards-compliant power adapter that is...

Combining PFC and constant-current output, the LYTSwitch-5 single-stage LED driver IC family has been introduced by Power Integrations. The devices achieve over 90% efficiency, 0.9 PF, less than 5% THD and ±3% current regulation accuracy over line, load, production variance, temperature and multiple topologies, making it suited for solid-state lighting applications below 25W.

Expanding its InnoSwitch IC family, Power Integrations has added a constant power version of the switching technology which combines primary, secondary and feedback circuits in a single surface-mounted off-line flyback switcher IC.

Power Integrations has announced the latest result in one of its ongoing patent cases against Fairchild Semiconductor. After a trial in federal district court in San Francisco, a jury awarded Power Integrations $139.8m in damages stemming from Fairchild’s infringement of two Power Integrations patents.

Using the magnetic inductive coupling principle, Power Integrations has introduced the InnoSwitch-EP family of off-line CV/CC flyback switching ICs and shifts focus from the charger market to the white goods market where reliability is expected to be 1pmm.  

Expanding its ChiPhy charger-interface IC family, Power Integrations has announced the first IC for off-line AC/DC chargers compatible with Qualcomm's Quick Charge (QC) 3.0 protocol. The QC 3.0 protocol implemented in the CHY103D device substantially reduces losses in the smart mobile device handset during rapid charging, enabling system designers to choose to charge handsets faster or reduce phone touch-temperature during charging.

Power Integrations has announced its HiperPFS-3 family of PFC ICs, which offer high power factor and high efficiency across the entire load range. Targeting applications with continuous power demands up to 405W for universal input and 900W for high-line, the ICs feature efficiency levels of better than 95% from 10% load to full load and consume less than 60mW under no-load conditions. A power factor of above 0.92 is easily achievable at 20% ...

Increasing design flexibility by covering a wide range of applications and output power, the CAPZero-2 X capacitor discharge ICs have been unveiled by Power Integrations. Featuring an expanded X capacitor range from 0.1 to 6µF and a 1kV breakdown voltage rating which allows for a transient voltage capability of 6kV, CAPZero-2 ICs withstand severe line surges and swells.

Power Integrations has announced the DER-479 reference design, which demonstrates an industrial power supply using the company’s LinkSwitch-4 family of CV/CC primary-side regulated switcher ICs with a 1200V Bipolar Junction Transistor (BJT). The design supports 440VAC line inputs and features three outputs, which combine to provide up to 11W of highly accurate constant-voltage DC power.

A dual-channel gate-driver core for 90kW to 500kW inverters and converters has been introduced by Power Integrations. Leveraging SCALE-2+ integrated circuit and isolated transformer technology for DC/DC power and switching signal transmission, the 2SC0115T2A0-12 driver core improves system reliability and performance by eliminating the need for an opto-coupler.

Based on the company’s InnoSwitch-CH family of integrated switcher ICs, Power Integrations has announced a reference design kit for a 10W CV/CC USB charger. RDK-420 enables users to build an 85-264VAC input smart mobile / USB charger with 5V, 2A output, measured in accordance with new US Department of Energy standards and European Union Code of Conduct Version 5, Tier 2 at the end of a USB cable.
