Description

The TNY277PN is part of the TinySwitch-III series from Power Integrations. It is an off-line switcher IC designed for use in low-power switch-mode power supplies (SMPS). This highly integrated IC combines a 700V power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown circuitry into a single device. The TNY277PN is ideal for creating compact, efficient, and cost-effective power supplies for a wide range of applications.

Features

  • Integrated High-Voltage MOSFET: The IC features a 700V power MOSFET integrated with control circuitry, reducing the need for external components and enabling more compact designs.
  • TinySwitch-III Technology: Provides advanced features such as auto-restart, frequency jittering, and enhanced efficiency, making it suitable for modern energy-efficient power supply designs.
  • Low Standby Power: Optimized to minimize standby power consumption, ideal for applications that need to meet stringent energy efficiency standards.
  • High Efficiency: Designed to deliver high efficiency across a wide range of load conditions, reducing power loss and heat generation.
  • Auto-Restart Protection: Includes auto-restart functionality for protection against output short circuits and open loops, enhancing the safety and reliability of the power supply.
  • Frequency Jittering: Helps reduce electromagnetic interference (EMI) by spreading the switching frequency, simplifying EMI filter design and aiding compliance with regulatory standards.
  • Thermal Shutdown: Protects the IC from overheating, ensuring reliable operation under various conditions.
