TNY256YN,Low Power Offline Switcher IC,TO-220-7B

The TNY256YN is part of the TinySwitch Plus family, designed to deliver an energy-efficient, low-cost solution for offline power supply applications. With its integrated 700V power MOSFET, the TNY256YN simplifies design by eliminating the need for a transformer bias winding and reducing component count. Its advanced control scheme offers fast transient response and tight voltage regulation.

Equipped with auto-restart, frequency jittering, and undervoltage lockout, the TNY256YN provides robust performance and meets international energy efficiency standards. The compact TO-220-7B package ensures ease of assembly and effective heat management, making it an ideal choice for adapters, battery chargers, and auxiliary power supplies.

• Integrated Design: Combines a 700V MOSFET, oscillator, and control logic in a single chip.
• Wide Input Voltage Range: Operates efficiently between 85V and 265V AC, supporting universal input applications.
• Energy Efficient: Consumes only 30mW at 115V AC and 60mW at 230V AC during no-load conditions.
• Built-In Protection: Includes overcurrent protection, thermal shutdown, and auto-restart for enhanced safety.
• Simple ON/OFF Control: Eliminates the need for loop compensation components, reducing design complexity.
• Compact TO-220-7B Package: Ideal for high-density PCB designs with effective heat dissipation.
