In today's world, where reducing environmental impact and enhancing efficiency are paramount, innovation is rapidly advancing in both the automotive and industrial equipment sectors. In response to this shift, new power solutions are becoming increasingly vital. A key common trend is the transition to 48V systems, trending to even higher voltage ranges. In this context, standard power products featuring noise immunity, low power consumption with up to 80V input range, along with unique solutions such as high voltage monitor ICs and leakage detection ICs, need to address the principles of 'Smarter, Smaller, Simpler.' Nisshinbo ICs achieve high reliability and precision beyond discrete configurations while significantly reducing component count and board space. Through these efforts, we deliver optimized, compact power systems and products that reduce engineers' workload by preventing unintended design revisions due to unforeseen issues, thereby driving technological progress.
