Tongjia launches LED backlight driver IC LD7889 with up to 93% efficiency

[High-tech LED News] Tongjia introduced a 4-channel LEDlight bar, a constant current LED backlight driver IC, the LD7889, with an efficiency of up to 93%.

It is understood that in the wide input voltage range of 4.5V to 36V, it can cooperate with various power sources to drive 12-90 LEDs to produce uniform brightness. The current driving capability of each channel in the IC can reach up to 330mA, and can apply future high-current LEDs. Light bar.

Focusing on larger LED monitors and smaller LED TVs, the LD7889 provides LED short-circuit and open-circuit protection, as well as output protection signals for LED malfunction detection, allowing the system to determine the LED light bar usage.

In addition, LD7889 has built-in innovative patented technology to meet the IC Thermal requirements for system requirements, so that the IC package temperature can be lower than the customer's specifications and power specifications for 3D dynamic pictures.
