Macroblock Introduces High Efficiency Non-Isolated AC / DC LED Driver- MBI6902 for T8 and E27 Applications and Low Power Consumption LED Display Driver MBI5035

Macroblock today comes up with two new LED drivers, the MBI6902 with superior efficiency in high brightness LED lighting applications, and the MBI5035, which features low knee voltage of 0.2V to reduce power consumption of LED displays.

Macroblock MBI6902:
Macroblock introduces a new non-isolated, step-down and high efficiency AC / DC LED driver, MBI6902, especially for T8 and E27 lighting applications. The MBI6902 achieves superior efficiency in high brightness LED lighting applications. For example, the efficiency is over 90% when lighting up 6-LEDs @ VAC =110V, 350mA. The MBI6902 is able to drive external MOSFET current up to 3A. In addition, the MBI6902 requires only a few external components. The high efficiency and compact solution of MBI6902 make it most applicable for T8, E27 and general illumination applications.

The MBI6902 accepts wide universal AC input from 80VAC to 265VAC and regulates the accuracy of preset output current within ±5% by switching the external MOSFET. Besides, the MBI6902 has multiple features to protect the controller from fault conditions, including under voltage lockout (UVLO), over voltage protection (OVP), over current protection (OCP), and LED open-circuit and short-circuit protection. Additionally, to ensure the system reliability, the MBI6902 is built with the thermal protection (TP) function. The MBI6902 is now available in MSOP-8L package. Samples and reference designs are now available. For more information, please contact us via email: marketing@mblock.com.tw.

Macroblock MBI5035:
In response to the trend of energy saving and environment protection, Macroblock launches the first low power consumption 16-bit LED display driver - MBI5035, which features low knee voltage of 0.2V to reduce power consumption of LED display as well as carbon emissions up to 35%.

"To implement the environmental protection concept, Macroblock presents MBI5035.” said Macroblock general manager Robert Chen. “LED display embedded with MBI5035 brings power saving and cost saving to advertisers. Facing with the worldwide rising electricity fees and energy saving requirement, MBI5035 is definitely the preferred LED display solution." he emphasized

LED display embedded with MBI5035 can reduce noise during system operation because of less power supplies and fans in LED display modules. Therefore, MBI5035 is more suitable for indoor
applications. With low knee voltage of 0.2V, MBI5035 features low driver temperature as well as the environment temperature. Therefore, MBI5035 can effectively enhance system stability and realize longer LED life time.

Traditional LED display drivers waste 35% of power in the form of heat. According to Macroblock statistics, 100 square meters of LED display adopting MBI5035 will reduce power loss by 35% as shown in the table below.

Electricity Fee

Traditional LED Display

(Embedded LED drivers:MBI5024)

Power-Saving LED Display (Embedded LED drivers:MBI5035)

Size of LED Display:100m2

USD$15,800

USD$10,270

Carbon Emissions

127600kg CO2/Year

82940kg CO2/Year

Note: The calculation is based on Co2 emission factor for American electric power: 0.549 kg CO2/kWh. Besides, the average U.S. industrial electricity fee for the year 2009 is USD$ 0.068/kWh.

MBI5035 adopts PrecisionDrive™ technology to enhance color accuracy and current uniformity. The design of staggered delay of output between channels can avoid inrush current and reduces EMI interference. MBI5035 is compatible with traditional MBI5024 in packages. LED display manufacturers can easily upgrade their LED displays with MBI5035 by optimizing power supply design.
