Cumulative Technology launched LED lighting with constant current mode DC/DC converter

Accumulation of science and technology successfully developed a highly efficient DC/DC - MBI6650 converter and traditional constant voltage mode DC/DC converter with different 1.2A constant current mode, and the use of Hysteretic PFM technology innovation, service life and efficiency improvement of current driving LED in lighting applications, has become the best scheme of LED lighting application.

Hysteretic PFM the accumulation of science and technology, in addition to avoid interference of the audio, and in the current state, the switching frequency is fast; in the small current, the switching frequency is slow, so that MBI6650 in the light load and heavy load system conversion efficiency was as high as 85% and 90%, significantly enhance the efficiency of operation the LED lighting system, to achieve energy saving effect.

MBI6650 is a TO-252-5L package and requires only four external components of the driver chip, which can reduce the size of PCB, effectively reduce costs. For high power LED lighting applications, this chip input current range also expanded to 9 to 36V. In addition, MBI6650 built-in full range of protective measures and heat sinks, MBI6650 can improve the stability and safety of the operation.
