Features

• Integrated High-Voltage Power MOSFET: Includes a high-voltage power MOSFET that can directly switch from the high-voltage DC bus.
• Multi-Mode Operation: Supports continuous, discontinuous, and forced discontinuous conduction modes for optimal performance across a wide range of load conditions.
• High Efficiency: Optimized for high efficiency with low standby power consumption, often below 1W.
• Adjustable Current Limit: The current limit can be adjusted externally, allowing designers to optimize the power supply for specific applications.
• Frequency Jittering: Reduces EMI by spreading the switching frequency spectrum.
• Auto-Restart Protection: Automatically restarts the power supply after a fault condition, such as output short circuit or open-loop, reducing stress on components.
• Cycle-by-Cycle Current Limiting: Provides protection by limiting the peak current on a cycle-by-cycle basis.
• Thermal Shutdown: Protects the IC from overheating by shutting it down when the junction temperature exceeds a safe level.
• Under-Voltage Lockout (UVLO): Ensures that the IC only operates when the input voltage is within a safe range, preventing erratic behavior.
• Soft-Start: Reduces component stress by gradually increasing the duty cycle during startup.
• Built-in Protection Features: Includes over-voltage, over-temperature, and over-current protection to enhance the reliability and safety of the power supply.
