Features

• Integrated High-Voltage Power MOSFET: Combines a high-voltage MOSFET with the control circuitry, eliminating the need for external high-voltage components and simplifying the design.
• Multi-Mode Operation: Supports continuous, discontinuous, and forced discontinuous conduction modes to adapt to different load conditions and optimize performance.
• High Efficiency: Designed for high efficiency with low standby power consumption, making it ideal for energy-efficient power supplies.
• Adjustable Current Limit: The current limit can be adjusted externally, allowing customization based on the application’s requirements.
• Frequency Jittering: Helps reduce EMI by spreading the switching frequency, facilitating compliance with EMI regulations.
• Auto-Restart Protection: Automatically restarts after a fault condition, such as output short-circuit or overload, enhancing the reliability of the power supply.
• Cycle-by-Cycle Current Limiting: Provides protection by limiting the peak current during each switching cycle, ensuring safe operation.
• Thermal Shutdown: Protects the IC from overheating by shutting it down if the junction temperature exceeds a predefined threshold.
• Under-Voltage Lockout (UVLO): Ensures the IC operates only when the input voltage is within a safe range, preventing erratic behavior.
• Soft-Start: Gradually ramps up the duty cycle during startup to reduce inrush current and stress on components.
