AC DC Converters, Offline Switches

TNY267P Description

The TNY267P from Power Integrations is an obsolete but historically significant offline switcher IC designed for flyback topology applications. This through-hole-mounted device integrates a 700V breakdown voltage MOSFET, enabling robust performance in AC/DC converter designs. With a 19W power rating, 132kHz switching frequency, and 65% duty cycle, it offers efficient power conversion for low-to-moderate power requirements. The IC features isolated output and complies with REACH Unaffected and EAR99 regulations, making it suitable for global markets. Its 8DIP package simplifies prototyping and manufacturing.

TNY267P Features

• Integrated 700V MOSFET: Eliminates the need for an external switch, reducing BOM complexity.
• Comprehensive Protection: Includes current limiting, open-loop, over-temperature, and short-circuit fault protection for enhanced reliability.
• Control Features: EN (Enable) pin for precise power management.
• High Efficiency: 132kHz switching frequency minimizes transformer size while maintaining efficiency.
• Wide Operating Range: Supports universal input voltage (85VAC–265VAC) for global compatibility.
• Low Sensitivity: MSL 1 (Unlimited) ensures ease of handling in humid environments.

TNY267P Applications

• Consumer Electronics: Power supplies for set-top boxes, DVD players, and LED drivers.
• Industrial Systems: Auxiliary power for sensors, PLC modules, and control circuits.
• Household Appliances: Low-cost PSUs in smart home devices and battery chargers.
• Legacy Designs: Suitable for retrofitting or servicing older equipment requiring 19W isolated flyback solutions.

Conclusion of TNY267P

While obsolete, the TNY267P remains a benchmark for compact, integrated offline switchers in flyback designs. Its built-in protections, high-voltage capability, and simplified topology make it ideal for cost-sensitive, space-constrained applications. Engineers seeking drop-in replacements or evaluating legacy systems will find its balance of performance and integration valuable. For modern designs, Power Integrations' newer TinySwitch or InnoSwitch families may offer advanced alternatives.
