IGBT, MOSFET drivers get protective conformal coating
Power Integrations today introduced factory conformal coating for its SCALE IGBT and MOSFET drivers. Conformal coating enhances system reliability by protecting electronic components against contaminants such as pollution, dust and condensation, which may cause corrosion. Power Integrations’ factory-coated gate drivers reduce inventory cost, lead time and overall cost of ownership by eliminating the need for […]

Reference design covers no-neutral wireless wall switches for smart-home lighting
Typically, smart wall switches with wireless connectivity, occupancy/vacancy sensing and/or voice control require a neutral return wire to power the unit, which is not always available in retrofit situations. No-neutral products are available for legacy incandescent bulbs because the small AC input current that is allowed to leak through the load when the smart-switch is […]

Offline flyback switcher IC family carries 94% efficiency ratings
Pairing the latest sleek, sexy phone with a power adapter that screams “brick” simply doesn’t fly anymore for the consumer, nor does settling for anything but substantially noticeable charging times. But it’s one of the apparent sweet spots for Power Integrations’ latest offline CV/CC flyback switcher ICs in the InnoSwitch line. After all, what manufacturer or consumer […]
Future Electronics to distribute Power Integrations products
Power Integrations today announced a worldwide distribution agreement with Future Electronics, a global leader in the distribution and marketing of electronics components. Commented Ben Sutherland, vice president of worldwide sales at Power Integrations: “Power supply, lighting and IGBT sub-system developers using PI products will have access to excellent technical help and pre- and post-sales support […]
Reference design covers 12-W dimmable LED downlight with color management over Bluetooth
A new reference design, DER-612, describes a constant-voltage (CV), constant-current (CC) 12-W isolated flyback power supply with power factor correction for smart lighting applications. The design includes a 3.3-V power supply to drive a Casambi CBM-001 Bluetooth wireless module, which provides dimming and color management control of the four-string LED load from 0 to 400 […]
Gate-driver ICs target 480-690 Vac apps
SCALE-iDriver galvanically isolated single-channel gate driver ICs now support IGBT blocking voltages up to 1700 V, which are typically used in 480 to 690 VAC line applications. They are ideal for industrial drives, 3-level power supplies/UPS and photovoltaic inverters, commercial EV and traction auxiliary equipment. 1700 V SCALE-iDriver ICs deliver a gate current of up […]
Galvanically isolated single-channel gate driver ICs support IGBT blocking voltages to 1.7 kV
Power Integrations announced an expansion of its SCALE-iDriver™ family of galvanically isolated single-channel gate driver ICs. The new devices support IGBT blocking voltages up to 1700 V, which are generally used in 400 VAC and 690 VAC line applications. They are also ideal for the latest three-level topology photovoltaic inverters and for photovoltaic arrays leveraging […]
