NCP12400BBHAB0DR2G Description

Short technical summary and product information.

The NCP12400BBHAB0DR2G is a fixed-frequency current-mode controller manufactured by On Semiconductor, specifically designed for flyback converter applications. This device operates at a fixed frequency of 65kHz and supports an input voltage range from 8.9V to 28V.

 

Key features include soft-start control and protection against over load, over power, over temperature, and over voltage conditions. It is not an internal switch device and is designed for isolated output topologies. The controller is housed in a 7-SOIC package and is surface-mounted.

 

This component is suitable for applications requiring robust power supply designs, offering features like frequency foldback for efficiency in light load conditions and a dedicated off mode for low standby power consumption. Its high-voltage current source with brown-out detection simplifies VCC circuitry design.
