High-power LEDs challenge electronics engineers to design accurate and efficient, yet simple, driver circuits. Conventionally, driving high-power strings with accurate current requires dedicated ...

The high efficiency of more than 93 % at heavy load with 1 Ampere and three LEDs in series as well as 85 % at light load with 0.35 Ampere and one LED allows the usage of a very small PCB. The LED ...

LED replacement of incandescent lighting for residential use involves IC design that requires “penny pinching” to a degree not found in many other areas. LED-based bulbs that replace their ...

LED driver IC design house Macroblock has developed two new driver ICs used in automotive interior/exterior lighting, MBI6659Q and MBI6665Q, and has obtained AEC (Automotive Electronics Council)-Q100 ...

NEW DELHI: LED drivers are fluorescent lamps or transformers for low voltage bulbs. They provide the correct amount of power to LED bulbs to function without any problem. However, we have already ...

Diodes has released simple LED driving chips for regulating current in strings of LEDs, particularly in cars and other road vehicles – some of which match parts from Infineon and Nexperia (see table ...

Dimming LEDs is an important feature in many of today’s solid state lighting applications. While many implementations for dimming LEDs in the market today rely on PWM modulation of the LED driving ...

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 ...
