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 […]

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 […]
