NCP1340B1DR2G Description

Short technical summary and product information.

The NCP1340B1DR2G is a quasi-resonant flyback controller from ON Semiconductor, suitable for designing high-performance off-line power converters. It features integrated high-voltage startup with brownout detection and an active X2 capacitor discharge capability, enabling low no-load power consumption.

 

This controller operates within a wide VCC range of 9 V to 28 V and has a specified operating temperature range of -40°C to 125°C. Key protective features include internal brownout detection, non-dissipative Over Power Protection (OPP), latched overvoltage protection, and NTC-ready overtemperature protection. It also implements abnormal overcurrent fault protection for winding short circuit or saturation detection.

 

The NCP1340B1DR2G utilizes valley switching operation with valley-lockout for noise-free operation. It also features frequency foldback with a 25 kHz minimum frequency clamp for increased efficiency at light loads, and skip mode with quiet-skip technology for highest performance during light loads. The device is available in an 8-SOIC package and is surface mountable.

 

This controller is designed for applications requiring isolated power conversion. Its robust protection features and efficient operation at various load conditions make it a versatile choice for power supply designs.
