Product Description

The NCP12400B2DR2G is a high-efficiency B2DR2G power IC designed for offline power supply applications. This NCP12400 power regulator features a single input channel supporting universal AC mains (85-265 VAC) and delivers regulated DC output through external components. Operating within -40°C to +125°C, it integrates critical functions including brown-out protection, frequency jittering, and auto-restart for overload/short-circuit conditions. Widely used in industrial controls, consumer electronics, and auxiliary power systems, its fixed-frequency current-mode architecture ensures stable operation under variable loads. Key advantages include low standby power (<100mW) and robust thermal performance, while requiring external MOSFETs and passive components for implementation. The IC lacks direct communication interfaces but supports secondary-side regulation via optocoupler feedback. Battery capacity and screen parameters are not applicable to this power management solution.
