NCP13992 AC-DC Converters onsemi NCP13992 AC-DC Converters are high-performance current mode resonant controllers with integrated high-voltage drivers. These AC-DC converters offer a built-in brown-out input function to ease the implementation of the controller in all applications. The NCP13992 controllers provide protection features such as overload protection, over-current protection to prevent hard switching cycles, brown-out detection, open optocoupler detection, and automatic dead-time adjust. Typical applications include adapters and offline battery chargers, flat panel display power converters, computing power supplies, industrial, and medical power sources.
