车用LED驱动电路的研发及产业化是半导体照明产业链中不可缺少的极其重要的一个环节。在实际应用过程中,由于驱动电路自身的功耗和寿命问题,使得LED原有的优点得不到充分发挥;如果驱动电路的设计及驱动方式选择不当,使LED极易损坏。为此,LED驱动电路的优化设计成了业界关注热点。 Automotive LED driver circuit research and development and industrialization of the semiconductor lighting industry chain is an indispensable part of an extremely important link. In the actual application process, the original advantages of the LED can not be fully exerted due to the power consumption and lifetime of the driving circuit itself. If the driving circuit is improperly designed and driven, the LED can be easily damaged. To this end, the optimal design of LED driver circuit has become a hot topic in the industry.
