Features

• Integrated High-Voltage Power MOSFET: The IC includes a high-voltage power MOSFET that can switch high DC bus voltages directly, simplifying the design and reducing the need for additional components.
• Current-Mode Control: Provides stable operation with excellent line and load regulation, ensuring consistent performance.
• High Efficiency: Designed to minimize power loss, both in active mode and during standby, contributing to energy-efficient designs.
• Auto-Restart Protection: Automatically restarts the IC in case of fault conditions such as output short circuits, reducing the risk of damage to the power supply.
• Cycle-by-Cycle Current Limiting: Limits the peak switch current on a cycle-by-cycle basis, protecting the MOSFET from exceeding its safe operating area.
• Thermal Shutdown: Protects the IC from overheating by shutting it down if the junction temperature exceeds a safe threshold.
• Under-Voltage Lockout (UVLO): Ensures the IC only starts when the input voltage is within a safe range, preventing unstable operation.
• Wide Input Voltage Range: Capable of operating from a universal input range of 85V to 265V AC.
• Fixed Switching Frequency: Operates at a fixed frequency of 100 kHz, simplifying EMI design and ensuring predictable performance.
• Soft-Start: Reduces inrush current during startup, minimizing stress on components and enhancing the reliability of the power supply.
