    The NE1182 is a high-performance current-type half-bridge LLC controller with excellent system stability and optimized dynamic characteristics.
    The NE1182 integrates high-voltage start current source, half-bridge drive unit, X capacitor discharge and other circuit modules, and the IC periphery is simplified and the system material cost is low.
    The NE1182 can be optimized by selecting key indicator gears such as feedback gain curve through SETA and SETB pin resistance.
    The IC has adaptive dead zone regulation function to reduce the loss during the dead zone and improve the system efficiency.
    The NE1182 has a full range of protection features, including power supply UVLO protection, bus voltage Brown-out protection, cycle by cycle overcurrent protection, output short circuit protection, overpower protection, output overvoltage protection, external overtemperature protection, internal overtemperature protection, and LLC capacitor-mode protection. Different versions, its protection mode can be flexibly selected (lock, no lock).
