NCP12400BBAAA0DR2G Description

Short technical summary and product information.

The NCP12400BBAAA0DR2G from On Semiconductor is a fixed-frequency, current-mode controller specifically designed for flyback converter applications. This component simplifies auxiliary supply and VCC capacitor design through its Dynamic Self-Supply feature, which activates an internal startup current source during various operational states.

 

Key electrical specifications include a switching frequency of 65kHz, an 80% duty cycle, and an operating voltage range of 8.9V to 28V. It supports soft start control and offers comprehensive fault protection, including over load, over power, over temperature, and over voltage detection. The device operates within a temperature range of -40°C to 150°C (TJ).

 

This controller is housed in a 7-SOIC package and utilizes a surface mount configuration. It features isolated output and is supplied on tape and reel. The NCP12400BBAAA0DR2G is suitable for applications such as offline adapters for notebooks, LCDs, and printers, as well as offline battery chargers and consumer electronic power supplies.
