The onsemi NCP1129AP65G is a high-performance offline flyback converter designed for efficient power supply applications. This device operates at a 65kHz switching frequency and features an internal 650V power switch, simplifying external component count. The NCP1129AP65G supports a maximum power output of 43W and offers robust fault protection, including over-load, over-temperature, over-voltage, and short-circuit protection. Its wide operating voltage range for Vcc/Vdd (8.5V to 35V) and a startup voltage of 17V ensure reliable operation across various input conditions. The isolated topology, combined with a wide operating temperature range of -40°C to 150°C (TJ), makes it suitable for demanding industrial automation, consumer electronics, and lighting control systems. Supplied in a 7-PDIP package for through-hole mounting, this component facilitates ease of assembly in high-volume manufacturing.
