Constant current DC/DC converter for accumulating LED lighting
Accumulation Technology has successfully developed a 1.2A "constant current mode" high efficiency DC/DC converter, the MBI6650, which is different from the traditional "constant voltage mode" DC/DC converter, and uses the innovative HystereticPFM technology to improve the use of current-driven The longevity and efficiency of LEDs in lighting applications has become the best solution for LED lighting applications.
The HystereticPFM technology used by Accumulation Technology not only avoids interference with audio, but also switches at a high current state, and the switching frequency is fast. At low currents, the switching frequency is slow, which makes the MBI6650 switch between light and heavy loads. The efficiency is as high as 85% and 90% respectively, which greatly improves the efficiency of the operation of the LED lighting system and achieves the effect of power saving.
The MBI6650 is a driver chip that uses a TO-252-5L package and requires only four external components, thus reducing PCB size and reducing cost. For high-power LED lighting applications, the chip's input current range is also amplified to 9 to 36V. In addition, the MBI6650's built-in comprehensive protection measures and heat sinks can improve the stability and safety of the MBI6650 during operation.
