Power Integrations AC/DC Converter 3 A 8-Pin DIP-C 7.5W Through Hole TNY263PN

Power Integrations TNY263PN AC/DC Converter 3 A 8-Pin DIP-C is a compact and efficient power management IC designed for converting AC input voltage to regulated DC output. Featuring a maximum input voltage of 265V AC and output power rating of 7.5 watts, this device supports through-hole mounting and an 8-pin DIP-C package for easy integration into electronic assemblies.

Operating at a switching frequency of 132 kHz, the TNY263PN enables the use of smaller transformers, reducing overall size and cost. It employs a flyback topology and supports a maximum output current of 3 amperes, suitable for low-to-medium power electronic applications.

The device integrates a 700 V power MOSFET, oscillator, current limit, and thermal shutdown protection, providing a reliable and safe power supply solution. Additional features include automatic restart for short-circuit and open-loop fault protection, a programmable line undervoltage detect function to prevent power glitches, and frequency jittering to significantly reduce electromagnetic interference by approximately 10 dB.

The operating temperature range from -40°C up to 150°C makes the TNY263PN suitable for a wide range of industrial, laboratory, and commercial electronic systems. Its compact size (length 9.83 mm, width 6.6 mm, height 3.68 mm) facilitates space-saving circuit designs.

This converter belongs to the TinySwitch-II series, known for embedding power MOSFET and control circuitry in a monolithic device, eliminating the need for bias windings and additional components. While this model is not compliant with automotive standards and does not have specific approvals, it is an excellent choice for general power management in electronics manufacturing and HVAC control systems.
