CISPR25 Tested Automotive Tail Light Reference Design for Step-Up + Linear LED Driver Based Systems
Description
TIDA-00678 showcases an automotive LED tail light application (tail/stop: turn and reverse) by using TPS92630-Q1 linear LED driver powered by an upstream boost converter (TPS40210-Q1) which is directly supplied through a smart-reverse battery diode off the automotive battery voltage. The design includes EMI/EMC radiation and pulse tests conducted by CISPR25 and ISO 7637-2 and highlights potential cost savings and efficiency (power dissipation: system thermals). For a similar design with TPS92630-Q1 driven by a buck converter: see TIDA-00677.For a similar design with TPS92630-Q1 driven directly from a car battery: see TIDA-00679.
