Description

The TNY276PN is part of Power Integrations’ TinySwitch-III series, a line of highly integrated off-line switcher ICs designed for low-power switch-mode power supplies (SMPS). This IC integrates a high-voltage power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown circuitry into a single package. The TNY276PN is ideal for applications that require a compact, efficient, and reliable power conversion solution.

Features

  • Integrated High-Voltage MOSFET: Features a 700V power MOSFET integrated with control circuitry, simplifying power supply designs and reducing component count.
  • TinySwitch-III Technology: Offers advanced features like auto-restart, frequency jittering, and enhanced efficiency, making it suitable for modern energy-efficient designs.
  • Low Standby Power: Optimized to consume very low standby power, making it ideal for applications that must meet stringent energy efficiency regulations.
  • High Efficiency: Capable of delivering high efficiency across various load conditions, reducing energy losses and minimizing heat dissipation.
  • 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: Helps reduce EMI by spreading the switching frequency, simplifying the design of EMI filters and ensuring compliance with regulatory standards.
  • Thermal Shutdown: Includes thermal shutdown to protect the IC from overheating, ensuring reliable operation under a wide range of conditions.

Specifications

  • Input Voltage Range: 85V to 265V AC
  • Output Power:
    • Up to 23W in open frame designs
    • Up to 15W 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, such as mobile devices, laptops, and small appliances
  • Standby power supplies for TVs, monitors, and other home appliances
  • Battery chargers for portable devices and small electronics
  • Low-power industrial power supplies
