Quality Control: Learn More
The onsemi NCV1077STBT3G is a highly integrated offline flyback controller designed for efficient power conversion. This device operates at a fixed switching frequency of 100kHz and features an internal 670V power switch, simplifying external component count. The NCV1077STBT3G supports a maximum duty cycle of 69% and includes essential control features such as enable (EN), frequency control, and soft-start for smooth power-up. Robust fault protection mechanisms, including current limiting, overload, overvoltage, and short-circuit protection, ensure system reliability.
With its SOT-223 (TO-261) surface-mount package, the NCV1077STBT3G is suitable for high-density applications. This component is qualified to AEC-Q100 standards, indicating its suitability for automotive applications, and is designed for operation across an ambient temperature range of -40°C to 125°C. The non-isolated flyback topology facilitates compact power supply designs up to 25W. Typical applications include automotive auxiliary power supplies and general-purpose offline converters.
