Safety-isolated LED-driver ICs deliver flicker-free output up to 65 W
The LYTSwitch-6 family of safety-isolated LED-driver ICs target smart lighting applications. The new ICs deliver flicker-free output up to 65 W and feature up to 94% efficiency and as little as 15 mW standby power with configuration options for two-stage or single-stage PFC support. Targeting smart residential and commercial fixtures and low-profile ceiling troffers, LYTSwitch-6 […]
MOSFET and IGBT gate drivers deliver peak current of 5 A
Power Integrations introduced the newest member of its SCALE-iDriver IC family, SID1102K, a single-channel, isolated, MOSFET and IGBT gate drivers in a wide-body eSOP package. Featuring a peak drive current of up to 5 A, the new part is able to drive 300 A switches without boosters; external boosters can be used to cost-effectively scale […]
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 […]
PODCAST Balu Balakrishnan: Integrating energy efficiency into a new, power-world order
Leading the charge for energy efficiency designs through unique power conversions systems is less of a power play for this CEO and President than it is a way of life. Power Integrations’ Balu Balakrishnan has followed an entrepreneurial path lined with seemingly distracting detours but which eventually led to new innovations in power conversion. And […]
