Description

The TNY280PN is part of Power Integrations’ TinySwitch-III series, specifically designed for AC/DC converter applications. This IC integrates a high-voltage power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown into a single package. The TNY280PN is tailored for low-power switch-mode power supplies (SMPS), offering a compact and efficient solution for various power conversion needs.

Features

  • Integrated High-Voltage MOSFET: Features a 700V power MOSFET integrated with control circuitry, which reduces component count and simplifies the design process.
  • Tiny Switch-III Technology: Provides advanced features like auto-restart, frequency jittering, and enhanced efficiency for modern power supply designs.
  • Low Standby Power: Designed for very low standby power consumption, making it suitable for energy-efficient applications that meet stringent energy regulations.
  • High Efficiency: Achieves high efficiency across different load conditions, reducing power losses and heat generation.
  • Auto-Restart Protection: Includes auto-restart functionality to protect against output short circuits and open-loop conditions, enhancing safety and reliability.
  • Frequency Jittering: Helps minimize electromagnetic interference (EMI) by spreading the switching frequency, simplifying EMI filter design and aiding regulatory compliance.
  • Thermal Shutdown: Incorporates thermal shutdown to protect the IC from overheating, ensuring reliable operation under a range of environmental conditions.

Specifications

  • Input Voltage Range: 85V to 265V AC
  • Output Power:
    • Up to 40W in open frame designs
    • Up to 25W 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 consumer electronics, mobile devices, and small appliances
  • Standby power supplies for TVs, monitors, and other home electronics
  • Battery chargers for portable devices
  • Low-power industrial power supplies
  • Auxiliary power supplies for larger systems
