The onsemi NCP1050ST44T3G is a high-performance offline switching controller designed for flyback converter topologies. This surface-mount component, housed in a SOT-223 (TO-261) package, operates at a switching frequency of 44kHz with an internal switch capable of handling up to 40W. Key features include a 700V breakdown voltage and integrated fault protection mechanisms such as current limiting, open loop, overload, and over-temperature protection. The device requires a supply voltage (Vcc/Vdd) between 7.5V and 10V, with a startup voltage of 8.5V. Its high operating temperature range of -40°C to 150°C makes it suitable for demanding applications. This component is commonly utilized in power supply units for consumer electronics, industrial automation, and lighting systems. The NCP1050ST44T3G is supplied in Tape & Reel (TR) packaging.
