Description

The TNY274PN is part of the TinySwitch-III series from Power Integrations. It is an off-line switcher IC designed for low-power switch-mode power supplies (SMPS). The TNY274PN integrates a 700V power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown circuitry into a single IC. This IC is ideal for applications requiring a compact, cost-effective, and energy-efficient power supply solution.

Features

  • Integrated High-Voltage MOSFET: Combines a 700V power MOSFET with control circuitry, minimizing the need for external components and simplifying the design.
  • TinySwitch-III Technology: Offers enhanced features such as auto-restart, improved efficiency, and reduced standby power consumption.
  • Low Standby Power: Designed to achieve low standby power, making it suitable for energy-efficient designs compliant with modern energy regulations.
  • High Efficiency: Capable of delivering high efficiency across a wide range of load conditions, reducing power loss and heat generation.
  • Auto-Restart Protection: Provides auto-restart protection in the event of output short-circuits or open loops, enhancing the safety and reliability of the power supply.
  • Frequency Jittering: Incorporates frequency jittering to reduce EMI, facilitating compliance with stringent EMI standards.
  • Thermal Shutdown: Built-in thermal shutdown protects the IC from overheating, ensuring reliable operation in various conditions.

Specifications

  • Input Voltage Range: 85V to 265V AC
  • Output Power:
    • Up to 16W in open frame designs
    • Up to 11W 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: <50mW 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 mobile devices and consumer electronics
  • Standby power supplies for TVs, monitors, and home appliances
  • Battery chargers for small electronics
  • Low-power industrial power supplies
  • Auxiliary power supplies for larger systems
