Boost controller delivers 100:1 dimming ratio
Diodes Incorporated introduced the AL3353 LED/LCD 40V max input boost controller, applicable across a wide range of applications where a constant voltage or constant current are required to drive displays and backlights with a dimming ratio of 100:1. It is well suited for use as a backlight driver for LCD TVs, LCD monitors, and flat panel […]
Teardown: Simple approach characterizes modern LED bulbs
LED bulbs we examined are often simpler than those made four years ago, sometimes employing discrete transistors to handle tasks once done via chips. Leland Teschler, Executive Editor Back in 2015, we examined LED bulbs putting out the equivalent of 60-W incandescent bulbs. We recently obtained several new LED bulbs to see how things have […]
Basics of wireless power transmission design
Most consumer devices that transfer power over wireless links follow the Qi standard. The construction of these power transfer systems is simpler thanks to the availability of new reference designs. Contributed by IDT Inc. Examine the wireless charging setup used in the passenger compartment of most vehicles and you are likely to find a system […]
Programmable 12-channel RGB-LED driver enhances lighting effects for smart devices and wearables
With patented features to prevent distracting artifacts in “color-chasing” or “deep breathing” LED animation effects, the STMicroelectronics LED1202 12-channel LED driver enables smoother and more natural interactions with smart-home devices, wearable electronics, and small appliances. The LED1202 can store eight programmable patterns and sequences and operate independently of the main controller, enabling the host system to save […]
