汽车用卤素前照灯电源

发布人:kingrobot 时间:2012-05-25 收藏

This circuit example demonstrates using a SEPIC-based automotive halogen headlight power supply that improves bulb reliability while also ensuring optimum illumination. The design maintains 12V at headlight voltage over a 9V to 15V input voltage range. It works well up to 1Ω interconnection resistance. The Virtual Remote Sense capabilities of the LT4180 allows the LT3757 SEPIC converter to be placed in the passenger compartment, away from extreme under-the-hood environments, thus improving reliability.
