In the future, the convergence of automotive and electronics will create a new and complex automotive system. Cars will become computers on wheels. To power more electronic control systems, Richtek has tackled automotive power design challenges to meet the expectations of high quality, reliability and safety. 


Automotive power-supply architecture is constrained by severe conditions including extreme temperature fluctuations, critical input transient conditions, electromagnetic emissions and so on. Richtek’s automotive solutions are all AEC-Q100 standard qualified to ensure consistent product performance from -40°C up to 125°C. Our solutions with wide input range meet the ISO16750-2/ISO7637-2 international industry standard, providing stable and reliable voltage to handle engine cold crank profile down from 3V and load dump transients up to 60V. We solve EMI problems with the designs of external clock synchronization, spread spectrum and low-level radiation packages. 


Building on long-term quality management, we can ensure the best quality control from the very beginning of product development all the way to monitoring shipment records of delivery. We have defined the Mission Profile for the assessment of real application robustness and implemented the Failure Mode and Effects Analysis (FMEA) to ensure that potential problems have been considered and addressed during system operations. We will introduce the ISO26262 functional safety standard for product designs and the required development processes.
