A voltage multiplier is applied as a high source impedance, 36V, 300mA, 12W LED driver. The high source impedance is ideal for driving power LEDs because it accommodates variations in LED junction ...

Diodes Incorporated today announced the release of the AL8806 buck LED driver, capable of producing a constant current of up to 1.5A from voltage sources of between 6V and 30V. Suiting MR16, 12V and ...

Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...

High-brightness LEDs are an inexpensive, robust, and green replacement for halogen light bulbs. This Idea for Design shows you how to apply an AC LED driver to convert the usual 12 or 24 V AC ...

GlacialPower announces a new dual-mode LED driver powering LED lighting from 7W to 20W. Featuring either constant current or constant voltage operation, the LED driver mode and power output can be ...

Typical uses today include backlighting for LCD TVs, projectors, computer displays, camera flashes, and vehicle brake lights. All need constant-current LED drivers that are economical and offer high ...

Novosense Microelectronics announced a 24 channel automotive LED driver at PCIM in Nuremberg today. NSL21924 is a high-side driver, aimed at rear lights, exterior lights and general automotive ...

KP1601X is a high efficiency Buck LED power switch designed for LED backlight. It adopts quasi-resonant control mode and integrates accurate zero-crossing detection of inductor current, which can work ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...
