NCP1340B6DR2G Description

Short technical summary and product information.

The NCP1340B6DR2G from ON Semiconductor is a highly integrated quasi-resonant flyback controller. It is designed for high-performance off-line power converters and features a proprietary valley-lockout circuitry for stable valley switching. This controller supports a wide input voltage range of 9V to 28V and operates within an ambient temperature range of -40°C to 125°C.

 

Key features include integrated high-voltage startup with brownout detection, X2 capacitor discharge capability, and multiple protective features such as over-power protection (OPP), latched overvoltage, and overtemperature protection. It also implements frequency foldback with a 25 kHz minimum frequency clamp for increased efficiency at light loads and skip mode with quiet-skip technology to minimize acoustic noise.

 

The NCP1340B6DR2G is supplied in an 8-SOIC package suitable for surface mounting. Its design facilitates low no-load power consumption, below 30 mW, and includes features for reduced EMI signature through frequency jittering. The controller is ideal for applications requiring robust and efficient power conversion.
