The NCP1339FDR2G from ON Semiconductor is a highly integrated quasi-resonant flyback controller. It is designed to control rugged and high-performance off-line power supplies, particularly for adapter applications. This controller supports a wide VCC range from 10 V to 28 V and operates within an ambient temperature range of -40°C to 125°C.
Key features include a lossless start-up sequence, X2 capacitor discharge capability, and a power saving mode (PSM) for extremely low no-load power consumption. The device incorporates several protective features such as current limiting, overload protection, over-temperature shutdown, and over-voltage protection. Its quasi-resonant current-mode flyback stage utilizes proprietary valley-lockout circuitry for stable valley switching and frequency foldback for efficiency.
The NCP1339FDR2G is housed in a 14-SOIC package and is designed for surface mounting. Its topology is Flyback, and it provides isolated output. The controller is suitable for applications requiring robust and efficient power conversion.
