NCP1342ANDBDD1R2G Description

Short technical summary and product information.

The NCP1342ANDBDD1R2G is an offline flyback controller from On Semiconductor designed for isolated power supply applications. It operates from a supply voltage range of 9V to 28V with a typical start-up voltage of 17V. The controller uses a flyback topology and provides fully isolated output. Its switching frequency is 500kHz, supporting efficient power conversion.

 

The device integrates comprehensive fault protection including current limiting, over load, over power, over temperature, over voltage, and short circuit protection. Control features include enable (EN), frequency control, soft start, and synchronization (Sync), enabling flexible system design. The controller does not have an internal switch, requiring an external MOSFET.

 

The NCP1342ANDBDD1R2G is housed in a 9-SOIC package (10-SOP, 0.154" width, 9 leads) with surface mount mounting. It is supplied in tape and reel packaging for automated assembly. The operating temperature range spans -40°C to 125°C (junction), making it suitable for industrial and automotive environments.
