The NCP1339CDR2G from On Semiconductor is a highly integrated quasi-resonant flyback controller designed for rugged, high-performance off-line power supplies, particularly for adapter applications. It features a wide operating voltage range of 10V to 28V and operates across a temperature spectrum from -40°C to 125°C (TJ).
This controller supports a Flyback topology and includes essential fault protection mechanisms such as current limiting, overload, over-temperature, and over-voltage protection. The device is housed in a 14-SOIC package and is designed for surface mount applications. It also features an isolated output.
Key design elements include a proprietary valley-lockout circuitry for stable valley switching and a power saving mode enabling extremely low no-load power consumption. The controller integrates a high-voltage startup circuit with brown-out detection and offers features like X2 capacitor discharge capability.
