NCP1910B100DWR2G Description

Short technical summary and product information.

The NCP1910B100DWR2G from ON Semiconductor is a versatile combo controller designed for next-generation ATX and flat TV power supplies. It combines a 65 or 100 kHz Continuous Conduction Mode (CCM) Power Factor Controller with an LLC controller that includes a high-voltage driver.

 

This device operates within a 9V to 20V range and features a frequency of 100kHz. It offers advanced control features such as Power Good and Soft Start, along with fault protection including current limiting and over voltage protection. The controller supports adjustable frequency fold-back for improved light load efficiency and adjustable line brown-out protection.

 

Housed in a 24-SOIC package, the NCP1910B100DWR2G is designed for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ). The integrated high-voltage drivers and various protection features make it suitable for demanding offline power supply designs.
