NCP1129AP100G Description

Short technical summary and product information.

The NCP1129AP100G from ON Semiconductor is a high-voltage switcher IC for offline power supplies. It features a fixed-frequency, peak current mode controller integrated with a 650V, 5.5A MOSFET, offering a high level of integration.

 

Key electrical specifications include an operating voltage range of 8.8V to 35V, a typical operating frequency of 100kHz, and a maximum output power of 43W. The device supports a duty cycle of 80% and includes comprehensive fault protection against overload, over-temperature, over-voltage, and short-circuit conditions. It also offers frequency foldback down to 26kHz for improved light-load efficiency and features frequency jittering for EMI improvement.

 

This component is designed for through-hole mounting and comes in a 7-PDIP package. It is compliant with EPS 2.0 standards and operates within a temperature range of -40°C to 150°C (TJ). The device also provides less than 100 mW standby power at high line conditions.
