Description

The TNY268PN is part of Power Integrations’ TinySwitch-II series, designed for low-power off-line switch-mode power supplies (SMPS). It integrates a high-voltage power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown circuitry into a single IC. This integration allows for the design of compact, efficient, and cost-effective power supplies, making the TNY268PN ideal for applications where space and energy efficiency are critical.

Features

  • Integrated Controller and MOSFET: Incorporates a 700V power MOSFET and control circuitry, reducing the need for external components and simplifying the design process.
  • TinySwitch-II Technology: Provides accurate cycle-by-cycle current limiting, ensuring robust protection against over-current conditions and short circuits.
  • Low Standby Power: Optimized to consume very low standby power, making it suitable for applications that need to meet stringent energy efficiency standards.
  • High Efficiency: Capable of delivering high efficiency across various load conditions, reducing power loss and minimizing heat generation.
  • Auto-Restart Protection: Features auto-restart capability for fault protection, including output short-circuit and open-loop protection, enhancing the safety and reliability of the power supply.
  • Frequency Jittering: Reduces electromagnetic interference (EMI) by varying the switching frequency, helping to meet EMI regulations with simpler filtering requirements.
  • Thermal Shutdown: Equipped with thermal shutdown to protect the IC from overheating, ensuring reliable operation under various conditions.

  • Input Voltage Range: 85V to 265V AC
  • Output Power:
    • Up to 19W in open frame designs
    • Up to 10W in enclosed adapters
  • Switching Frequency: 132 kHz with frequency jittering
  • MOSFET Breakdown Voltage: 700V
  • Current Limiting: Integrated cycle-by-cycle current limiting for reliable protection
  • Standby Power Consumption: <150mW at 265V AC input
  • Efficiency: Typically greater than 80%
  • Operating Temperature Range: -40°C to +150°C (junction temperature)
  • Package: 8-pin PDIP (Plastic Dual In-line Package)

Applications

  • AC-DC adapters for consumer electronics
  • Standby power supplies for appliances, TVs, and monitors
  • Battery chargers for portable devices
  • Low-power industrial power supplies
  • Auxiliary power supplies for larger systems
