Accumulation of step-down, high efficiency AC DC (AC - DC) LED control chip MBI6901

In coping with the global trend of energy saving, and LED to replace the traditional fluorescent lamp market potential, accumulation of science and technology for LED fluorescent lamp type T-8 lamp, LED lamp, LED light Kan (Light PanEL) application launch buck, high efficiency, non isolated AC to DC (AC-DC) LED control chip -MBI6901. MBI6901 can accept the AC input voltage of the full range (80VAC ~265VAC), to provide light high power LED stable output current control MOSFET switch by external to 3 amperes, and the current variation in the accuracy of + 5%, LED lamps can provide current stable, in order to increase the stability of LED lighting system.

Due to the LED fluorescent lamp power consumption is only 1/3 of the traditional fluorescent lamp, life is also the traditional fluorescent lamp 10 times, so the future of LED fluorescent lamp instead of traditional fluorescent lamp market can not be underestimated. MBI6901 accumulation of science and technology provided by hysteresis frequency modulation (Hysteretic PFM) architecture can effectively improve the power conversion efficiency at light loads, such as driving in six LED, AC voltage at 110 volts, 350mA (MA) when the current efficiency is above 90%, can achieve the benefits of saving power.

The MBI6901 provides a solution for the accumulation of EN55015 with low electromagnetic interference, electromagnetic interference testing through lighting fixtures, and through the international safety standards UL/CSA/IEC 60950-1. MBI6901 has a full range of protection features, including over voltage protection (UVLO), overheating protection, open circuit and short circuit protection, etc.. In addition, over voltage protection (OVP) can be achieved through the built-in voltage comparison mechanism to protect against excessive input voltage on the control chip damage. MBI6901 currently offers small package MSOP-8L package.

Accumulation of science and technology will be 7/22 in Beijing, 7/24 in Shanghai and 7/28 held the International Symposium on LED technology in Shenzhen, will be invited to visit the foreign traffic display, screen manufacturers will also share the accumulation of speech, how AC-DC drive selection for general lighting solutions. The first year of accumulation for the accumulation of lighting product line positioning in 2009, about LED lighting as the hope for the future of green lighting, have launched related lighting products to meet the market demand, including general lighting applications, All-Ways-OnTM series of MR16 lighting applications etc..
