TNY284DG

TNY284DG Description

The TNY284DG from Power Integrations is a highly integrated offline switcher IC designed for flyback topology applications, offering robust performance in a compact surface-mount 8SO package. With a 725V breakdown voltage and built-in MOSFET switch, it delivers up to 6W of power with high efficiency (up to 67% duty cycle) and operates at a switching frequency of 124kHz–140kHz. The device complies with RoHS and REACH standards, ensuring environmental safety, and features a Moisture Sensitivity Level (MSL) 1 rating, making it suitable for extended storage.

TNY284DG Features

• Integrated 725V MOSFET for high-voltage handling and reliability.
• Comprehensive fault protection: Current limiting, open-loop, over-temperature, over-voltage, and short-circuit protection enhance system durability.
• EN control feature for precise power management and standby mode optimization.
• Isolated output ensures safety in AC/DC conversion applications.
• Wide switching frequency range (124kHz–140kHz) reduces EMI and improves efficiency.
• Compact 8SO package saves board space while supporting surface-mount assembly.

TNY284DG Applications

The TNY284DG is ideal for low-power offline SMPS designs, including:

• Auxiliary power supplies for industrial and consumer electronics.
• Smart home devices (e.g., IoT hubs, smart plugs).
• LED drivers and adapter/charger circuits requiring high efficiency and isolation.
• Appliance control modules where reliability and fault protection are critical.

Conclusion of TNY284DG

The TNY284DG stands out for its high integration, robust protection features, and energy-efficient performance, making it a superior choice for compact, isolated power supplies. Its 725V MOSFET, fault resilience, and EN control provide a competitive edge over similar offline switchers, particularly in cost-sensitive, space-constrained applications. Engineers designing low-power AC/DC systems will benefit from its reliability and ease of implementation.
