The LED backlight in an LCD panel is the biggest power hog in notebook and tablet applications. As screen resolution and brightness level increase, the input power consumed by the LED backlight ...

This is a reference design for an LED display-backlight driver. The design uses a boost power supply with adaptive feedback for efficiency and linear current sinks for a high dimming ratio (2000:1).

Several driver options are at the fingertips of designers with the FAN56XX family of LED drivers from Fairchild Semiconductor. For instance, driver-only parallel connection drivers with no boost ...

Different topologies used in developing LED drivers. Proper connections for buck, boost, and buck-boost configurations. Test results for the three topologies using the same LED string. 3. This LTM8042 ...

PLANO, Texas--(BUSINESS WIRE)--Diodes Incorporated (Nasdaq: DIOD) today introduced the AL3353 LED/LCD 40V max input boost controller, applicable across a wide range of applications where a constant ...

AL8871Q is an LED driver qualified to AEC-Q100 Grade 1 and supporting the automotive PPAP (production part approval process). Its buck-boost topology allows it to operate from supplies across 8 – 60V ...

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 ...

Aiming at powering LEDs in automotive applications, Taiwan Semiconductor has introduced a dc-dc controller chip that can be operated in boost, buck-boost and sepic topologies from rails between 4.5V ...

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 ...
