The NCP1239ED65R2G is a fixed-frequency, current-mode controller for flyback converters manufactured by On Semiconductor. It features a high-voltage start-up current source for efficient power-on sequences and operates with a supply voltage range of 8.8V to 35V.
This controller supports a 65kHz switching frequency with frequency foldback down to 26kHz and skip mode for optimized light-load efficiency. It includes adjustable over-power protection (OPP), internal slope compensation, and internal fixed soft-start. Fault protection includes current limiting, over load, over temperature, and over voltage detection.
The NCP1239ED65R2G is housed in a 7-SOIC package and is designed for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ). The device offers ±500 mA peak source/sink drive capability and features internal thermal shutdown for robust operation.
Typical applications include AC-DC converters for TVs, set-top boxes, printers, and offline adapters for notebooks and netbooks.
