IC OFFLINE SWITCH FLYBACK 7DIPManufacturer: onsemi
Categories: AC DC Converters, Offline Switches
Quality Control: Learn More
The onsemi NCP1129BP65G is an isolated offline flyback converter designed for efficient power supply applications up to 43W. This component operates with a fixed switching frequency of 65kHz and features an integrated 650V power switch. The device supports a wide input voltage range from 8.5V to 35V, with a startup voltage of 17V. Advanced fault protection mechanisms are built-in, including overload, over-temperature, over-voltage, and short-circuit protection, ensuring robust operation. The NCP1129BP65G is packaged in a 7-pin PDIP (Plastic Dual Inline Package) for through-hole mounting and operates across a wide temperature range of -40°C to 150°C. Its flyback topology and internal switch simplify design for AC-DC conversion in consumer electronics and industrial power supplies.
