Teardown: The super-adjustable Ketra A20 LED bulb
Ketra unapologetically charges $100 for its A20 LED bulb, and the bulb needs a controller to work. Here’s what you find inside the bulb that makes it worth the premium price. A tunable A20-style LED light bulb from Ketra, in Austin, Tex., may be the world’s most expensive classic LED bulb. It lists at about […]
Power management ICs feature single-inductor multiple-output buck-boost regulators for wearables and hearables
Designers of Bluetooth headphones, activity monitors, smart garments, smartwatches, and other size-constrained devices can now increase battery life and efficiency using the MAX77650 / MAX77651 power management ICs (PMICs) from Maxim Integrated Products, Inc. Size is critical for hearables and wearables as they continue moving to smaller form factors. Most PMICs for these small, lithium-ion […]

LEDs mimic the natural spectrum of the sun for Circadian rhythm-optimized light
Seoul Semiconductor, a global innovator of LED products and technology, has developed a new LED technology that produces light that closely matches the spectrum of natural sunlight. Announced at a press conference in Frankfurt, Germany on June 26, 2017, the new SunLike Series natural spectrum LED technology was co-developed by Seoul Semiconductor and Toshiba Materials […]
High-voltage ac LED driver needs no diode bridge
LSI/CSI announces the availability of a powerful, all-inclusive new system level, High Voltage LED Dimmable Driver IC. Designated LS9100 Archimedes Series, this high-performance, low cost IC has a rugged design optimized for driving LED banks directly from the main utility line which eliminates the previously required, expensive and bulky AC-DC Power Supplies formerly used to drive LEDs. […]
Energy processing units reduce dynamic switching, static leakage power components
Sonics, Inc., introduced ICE-P3, the IP industry’s first product to automate implementation of dynamic voltage and frequency scaling (DVFS). ICE-P3 is the newest member of the ICE-Grain Family of Energy Processing Units (EPU) that identifies, sequences, and controls power state transitions in hardware up to 500X faster than conventional software-based approaches. ICE-P3 includes all of the capabilities […]
High-side smart power switch ICs for automotive applications
Car makers want in-vehicle electronic systems to provide a large number of energy-efficient functions in as little space as possible. Infineon Technologies AG supports this trend with its new power IC manufacturing technology SMART7. Infineon designed it specifically for automotive applications such as Body Control Modules or Power Distribution Centers. SMART7 power ICs drive, diagnose and protect […]
Photo control assemblies rugged enough for street lights
TE Connectivity is unveiling several innovations to its LUMAWISE photo control portfolio providing street lighting manufacturers additional design flexibility. TE’s LUMAWISE base assembly, sleeve and covers together integrate power and signal interface to the dimming receptacle to ensure long-term reliability. This interface can be used in applications such as LED outdoor roadway, street and area lighting […]
What’s all this stuff about capacitive power supplies for LEDs?
A while back a viewer of our 60-W LED bulb teardowns posted a comment about the complexity of the power supplies found in the bases of these bulbs. We talked about some of the reasons these bulbs contain switching supplies in a previous article. But our latest post elicited this comment from another reader: Well, […]
