Description

The TOP224YN is intended for use in a wide range of power supply designs, from small adapters to medium power supplies. It can operate directly from a rectified AC line, making it suitable for universal input power supplies. The IC is designed for high efficiency and reliability, with built-in features that protect against fault conditions.

Features

  • Integrated High-Voltage Power MOSFET: The device includes a high-voltage power MOSFET capable of switching high DC bus voltages directly.
  • Current-Mode Control: Provides stable operation and excellent line and load regulation.
  • High Efficiency: Optimized for low power consumption, both in active mode and during standby operation.
  • Auto-Restart Protection: Protects the IC and the power supply in fault conditions, such as output short circuits or overloads.
  • Cycle-by-Cycle Current Limiting: Prevents the power MOSFET from exceeding its safe operating area by limiting the peak current.
  • Thermal Shutdown: Automatically shuts down the IC if the junction temperature exceeds a safe threshold, protecting it from overheating.
  • Under-Voltage Lockout (UVLO): Ensures the IC only starts when the input voltage is sufficient, preventing unstable operation.
  • Wide Input Voltage Range: Suitable for universal input (85V to 265V AC).
  • Fixed Switching Frequency: Operates at a fixed frequency of 100 kHz for predictable EMI performance and design.
  • Soft-Start: Limits inrush current and reduces stress on components during startup.

Specifications

  • Input Voltage Range: 85V to 265V AC (universal input).
  • Output Power: Typically up to 180W (depending on design and thermal management).
  • Switching Frequency: 100 kHz.
  • Drain Current: Capable of handling up to 4.4A.
  • Output Voltage Regulation: 5% typical.
  • Standby Power: Less than 1W for energy-efficient designs.
  • Package: TO-220, providing robust thermal management with the option to attach a heatsink.

Applications

  • AC-DC adapters for consumer electronics (e.g., laptop chargers).
  • Standby power supplies for TVs, computers, and other appliances.
  • Industrial control power supplies.
  • Battery chargers and LED drivers.
