The NCP1239AD100R2G is a fixed-frequency current-mode controller from ON Semiconductor, specifically designed for flyback converter applications. This device features a high-voltage start-up current source for efficient power-on sequences.
Key electrical specifications include a supply voltage range of 8.8V to 35V and a typical switching frequency of 100kHz. It supports frequency foldback down to 26kHz and skip mode for optimized light-load efficiency. The controller includes features like internal slope compensation, fixed soft-start, and frequency jittering.
For protection, the NCP1239AD100R2G incorporates adjustable over-power protection (OPP), brown-out detection, and a 64ms timer-based short-circuit protection with auto-recovery or latched operation options. It also has internal thermal shutdown.
This component 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).
