A logic level N-channel high power MOSFET is used to create this RGB LED driver that would allow LED arrays or lamps of up to 5A per channel to be controlled without heatsink installed. A PIC16F863 is ...

This dimming controlled LED driver circuit is designed using LM3409 P-channel MosFET controller for step-down (buck) current regulators.The LM3409 devices use Constant Off-Time (COFT) control to ...

Automotive incandescent bulbs have largely given way to more efficient, reliable, stylish, and even safer light emitting diodes (LEDs). LEDs turn on in a fraction of the time and are especially useful ...

IXYS Integrated Circuits Division (ICD), Inc., has announced the availability of the FDA217, an optically isolated, dual photovoltaic MOSFET driver. Each independent driver consists of an LED that is ...

In many consumer applications for lighting the cost of existing technology – namely incandescent light bulbs or fluorescent tubes – is so low that LED lighting’s many advantages simply cannot make up ...

Light-emitting diodes have become the lighting source of choice for almost all illumination applications. Incandescents, fluorescents, CFLs, and other types are fading away in favor of the almighty ...

LED driver designs can deliver flicker-free and fast startup dimming performance while still providing high power factor and efficiency, writes Rich Miron Dimming performance of LED lamps in legacy ...
