First Components introduces high-efficiency DC/DC converter for high power LED lighting

München, (PresseBox) - To enhance the reliability of high power LED lighting applications, First Components introduces the 1.2A constant current buck DC/DC converter, MBI6650 by Macroblock. By means of constant current mode hysteretic PFM design, the converter answers the urgent call for traditional voltage mode DC/DC converter replacement since LED applications should be, in truth, powered by current source.

Applying constant current, the hysteretic PFM control scheme enhances system stability and optimizes excellent power efficiency up to 90% at heavy loading and even 85% at light loading. By comprising the features of adaptive output switching frequency and an audio frequency skip, both higher current and frequency can be reached as well as preventing customers from noise interruption when the MBI6650 is activated.

The MBI6650 is built with only 4 external components required and therefore successfully minimizes the PCB layout area, achieving the cost effectiveness. The design is available to operate over an input of 9 to 36V for high power LED applications. With full protection, the MBI6650 enhances power dissipation with a thermal pad in a TO-252-5L package.

The MBI6650 has achieved great improvement in the DC/DC buck converter in terms of high efficiency performance, system reliability, and power consumption reduction in the LED lighting industry for future high power LED applications.
