Features

• Integrated High-Voltage Power MOSFET: Combines a high-voltage MOSFET with control circuitry in one package, which simplifies the power supply design and reduces component count.
• Multi-Mode Operation: Supports continuous, discontinuous, and forced discontinuous conduction modes to optimize performance for various load conditions.
• High Efficiency: Designed for high efficiency, with low standby power consumption, making it ideal for energy-efficient designs.
• Adjustable Current Limit: Allows for external adjustment of the current limit, providing flexibility to match the specific needs of the application.
• Frequency Jittering: Reduces EMI by spreading the switching frequency spectrum, which helps in meeting EMI compliance requirements.
• Auto-Restart Protection: The IC automatically restarts after fault conditions such as an output short circuit or overload, which enhances reliability and protects the power supply.
• Cycle-by-Cycle Current Limiting: Limits the peak current on a cycle-by-cycle basis to protect the MOSFET and ensure safe operation.
• Thermal Shutdown: Provides protection by shutting down the IC if the junction temperature exceeds a specified threshold, preventing overheating.
• Under-Voltage Lockout (UVLO): Ensures that the IC only operates when the input voltage is within a safe range, preventing erratic behavior and ensuring stable operation.
• Soft-Start: Gradually increases the duty cycle during startup to minimize inrush current and reduce stress on power supply components.
