Description

The TOP223YN is designed for low-cost, low-power, and compact power supplies. It is particularly well-suited for applications requiring high efficiency and reliability, such as AC-DC converters, adapters, and standby power supplies. The device operates directly from a rectified AC line and does not require a large number of external components.

Features

  • Integrated High-Voltage MOSFET: The device includes a high-voltage power MOSFET, allowing it to switch directly from the high-voltage DC bus.
  • Current-Mode Control: Provides superior performance and stability in power supply designs.
  • High Efficiency: Optimized for efficiency, with low standby power consumption.
  • Auto-Restart Protection: Protects the power supply during fault conditions such as output short-circuit or open-loop.
  • Cycle-by-Cycle Current Limiting: Limits peak switch current on a cycle-by-cycle basis for improved reliability.
  • Thermal Shutdown: Over-temperature protection automatically shuts down the device when it overheats.
  • Under-Voltage Lockout (UVLO): Ensures proper startup by locking out the device if the supply voltage is too low.
  • Wide Input Voltage Range: Capable of operating over a wide range of input voltages, suitable for universal input applications (85V to 265V AC).
  • Frequency: Fixed switching frequency of 100 kHz.
  • Soft-Start: Reduces stress on the power supply during startup, enhancing reliability.

Specifications

  • Input Voltage Range: 85V to 265V AC (universal input).
  • Output Power: Typically up to 150W (depending on application and design).
  • Switching Frequency: 100 kHz.
  • MOSFET Drain Current: Up to 3.3A.
  • Output Voltage Regulation: 5%.
  • Standby Power: Less than 1W.
  • Package: TO-220, which provides good thermal performance and allows the use of a heatsink.

Applications

  • AC-DC adapters for consumer electronics.
  • Standby power supplies for computers, TVs, and appliances.
  • Industrial control power supplies.
  • Battery chargers.
  • LED drivers.
