onsemi Integrated Circuits (ICs) - Power Management (PMIC) - AC DC Converters, Offline Switches NCV1362ABDR2G

The NCV1362ABDR2G is a primary side quasi-resonant flyback controller designed for automotive applications. It features a highly integrated design that eliminates the need for secondary feedback circuitry, allowing for constant voltage and constant current regulation with excellent line and load performance. The controller operates in valley lockout quasi-resonant peak current mode at high loads to enhance efficiency and automatically adjusts the duty cycle at lower loads, entering pulse frequency modulation to maintain output regulation. This device is AEC-Q100 qualified, with a temperature range of -40¬8C to +125¬8C and a high-voltage capability of up to 28V. It includes multiple protection features such as output voltage under-voltage and over-voltage protection, cycle-by-cycle peak current limit, and short-circuit protection. The NCV1362ABDR2G is optimized for light load efficiency and has a low start-up current, making it suitable for automotive auxiliary power supplies and on-board chargers. The product is available in a Pb-free SOIC-8 package.
