LED-Drivers


Self-explanatory quality. A selection of power-management-ICs and constant-current-LED-driver-ICs supplement the ultimate performance of LEDs for LED-displays, -backlighting and general lighting. Including PWM, error detection and thermal protection device. Excellent dimming-linearity, precise output current, analog-/digital- or push-dimming, as well as a high efficiency of up to 97% speak for themselves.
NanoDriver

The products of the Acrich Nano driver series from Seoul Semiconductor with an area of 13.5 mm² are the smallest LED drivers in the world. Due to their miniaturized design, they are ideal for the design of..: Downlights, spotlights, tracklights as well as wall lights and recessed lights. Only very few external components are needed to connect the nano driver to build a complete luminaire that meets the requirements of California Title 24.

MicroDriver

The products of the Acrich Micro driver series from Seoul Semiconductor are up to 10 times smaller than comparable LED drivers. Due to their miniaturized design they are ideal for the design of: Downlights, spotlights, tracklights as well as wall lights and recessed lights. The Micro LED driver contains the even smaller brother "NanoDriver" with the necessary circuitry and is ready for use. With the Microdriver, complete luminaires can be mounted that meet the requirements of California Title 24.

✓ Extremely small size ✓ Very low flicker ✓ Phase section/angle control or analogue dimming ✓ Low inrush current ✓ High power factor ✓ EMC according to class B ✓ IP66

Generetic Constant Current LED Driver
PrecisionDrive™ technology enhances the characteristics of current output and current accuracy, allowing viewers to enjoy a clear and refined image on the LED display. Driver ICs with this technology has a +/- 1.5% current accuracy between output ports within each driver IC and a +/-1.5% deviation between driver ICs. The current varied with LED forward voltage change is no more than 0.1% per volt while the current varied with supply voltage change and ambient temperature change is restricted to 1%.
Multifunctional LED Driver
Share-I-O™ technology features pin compatibility. Share-I-O™, additional functions can be added to LED drivers without adding extra pins and changing the printed circuit board (PCB) originally designed for conventional LED drivers.
S-PWM LED Driver
The Scrambled Pulse Width Modulation (S-PWM) technology enhances Pulse Width Modulation (PWM) by scrambling an image into several sub-images with the same color quality. Besides increasing the image refresh rate, this feature also supports flicker-free image and improves reliability when building a 16-bit grayscale LED display.
SRAM Embedded S-PWM LED Driver
Overcoming the Seven Challenges Encountered in Fine-Pitch LED Displays. When it comes to delivering fine-pitch displays with top-notch performance, no one is more committed than Macroblock in finding ways to overcome the seven most common problems namely, ghosting effect, color shift at low grayscale, non-uniformity at low grayscale, dim line at first scan line, gradient dim line, LED dead pixel, and high contrast interference.
RGB LED Driver
  • Data Transmission Mode: Forward Direction Transmission.
  • Error Report Mode: Reverse Direction Transmission.
    • In traditional designs, the error report feature is achieved by connecting one additional wire from the last IC to the controller and a signal buffer. With I/O Bi-Directional Transmission, the same wire connecting the controller to the ICs is used to report information back to the control system. This not only improves communication between control systems and light fixtures but also saves wire costs.
DC/DC Converter and Controller
DC/DC converters and controllers are designed for LED lighting applications that require large power consumption. The constant current and high power efficiency meet the safety and reliability standards required by different applications.
AC/DC Converter and Controller
AC/AC converters and controllers are designed for LED lighting applications that require large power consumption. The constant current and high power efficiency meet the safety and reliability standards required by different applications.
All-Ways-On™
With constant current technology, the All-Ways-On™ series features instant on/off control of LED drivers. By adjusting the output current through a resistor and setting the LED brightness through the Pulse Width Modulation (PWM), the All-Ways-On™ series provides simple and reliable control of LED operation. Built-in thermal protection function is also added to the All-Ways-On™ series LED drivers to prevent ICs from overheating.

LED Display Driver

As the leading supplier in LED display driver ICs, Macroblock products have been chosen and applied towards various world-class events, landmarks, as well as venues with specific demands and strict requirements such as control rooms.
