TNY278PN Description

Short technical summary and product information.

The TNY278PN from Power Integrations is an energy-efficient, offline switcher belonging to the TinySwitch-III family. This IC is designed for flyback topology and features a voltage rating of 700V. It offers a power output of up to 28W and operates at a frequency of 132kHz.

 

This component is suitable for various applications requiring efficient power conversion. It is housed in an 8-PDIP-C package and supports through-hole mounting. The operating temperature range is from -40°C to 150°C (TJ).

 

Key features include selectable current limit, frequency jittering for reduced EMI filter costs, and enhanced safety features like accurate hysteretic thermal shutdown protection with automatic recovery. It also provides improved auto-restart for fault conditions and line undervoltage detect.

 

The TNY278PN is designed for ease of use, with simple ON/OFF control and no need for loop compensation. Its pin-out simplifies heatsinking to the PCB, and the SOURCE pins are electrically quiet for low EMI.
