Description

The TNY275PN is part of Power Integrations’ TinySwitch-III series, designed for creating efficient, low-power switch-mode power supplies (SMPS). This IC integrates a 700V power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown circuitry into a single compact package. The TNY275PN is well-suited for applications where compact design, high efficiency, and low standby power are essential.

Features

  • Integrated High-Voltage MOSFET: Combines a 700V power MOSFET and control circuitry, reducing the need for external components and simplifying power supply design.
  • TinySwitch-III Technology: Provides advanced features like auto-restart, frequency jittering, and enhanced efficiency, making it ideal for modern energy-efficient designs.
  • Low Standby Power: Designed to minimize standby power consumption, making it suitable for applications that require compliance with stringent energy efficiency standards.
  • High Efficiency: Delivers high efficiency across a wide range of load conditions, reducing power loss and heat generation.
  • Auto-Restart Protection: Includes auto-restart functionality to protect against output short circuits and open-loop conditions, ensuring safe and reliable operation.
  • Frequency Jittering: Reduces EMI by spreading the switching frequency, simplifying EMI filter design and helping to meet regulatory standards.
  • Thermal Shutdown: Protects the IC from overheating, enhancing the durability and reliability of the power supply.

Specifications

  • Input Voltage Range: 85V to 265V AC
  • Output Power:
    • Up to 19W in open frame designs
    • Up to 13W 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, laptops, and consumer electronics
  • Standby power supplies for TVs, monitors, and home appliances
  • Battery chargers for portable electronics and small devices
  • Low-power industrial power supplies
  • Auxiliary power supplies for larger systems
