Power Integrations AC/DC Converter 3 A, 12V, 9W, 7-Pin DIP TinySwitch-II TNY264PN

Power Integrations TNY264PN is a compact AC/DC Converter designed to deliver up to 3 A current with 12V output voltage and 9W output power. Featuring a 7-pin DIP package with through-hole mounting, this device belongs to the TinySwitch-II series integrating a highly efficient flyback topology.

This converter includes a built-in 700 V power MOSFET, oscillator, current limit, and thermal shutdown circuits, ensuring reliable performance and protection. Start-up and running power are sourced directly from the DRAIN pin voltage without needing an additional bias winding circuitry.

The device supports a broad input voltage range from 85V minimum to 265V maximum, suitable for various AC mains voltages. Its switching frequency of 132 kHz reduces transformer size, enabling a compact design using EF12.6 or EE13 cores, ideal for cost-sensitive consumer and industrial applications.

Protection features such as fully integrated auto-restart protect against short circuits and open loop faults, reducing external component count. Programmable line under-voltage detection prevents power on/off glitches, enhancing system stability.

Frequency jittering lowers electromagnetic interference (EMI) by approximately 10 dB, minimizing the need for expensive EMI filter components. The device practically eliminates audible noise with standard dip-varnished transformers, enhancing user experience in end products.

The product operates reliably within a temperature range from -40°C up to a maximum of 150°C, making it suitable for demanding industrial and commercial power supply designs.

Compliance with ENERGY STAR, EU regulations, and California Energy Commission requirements confirms its suitability for energy-efficient designs. Applications include power supplies for electronic devices, industrial automation, and consumer electronics requiring efficient, compact AC to DC conversion.

This AC/DC converter delivers 3 A continuous current with up to 9W power output. Wide input voltage range from 85V to 265V AC ensures versatile usage. Integrated protections enhance reliability and reduce external parts.

Compact 7-pin DIP package for easy integration into through-hole PCB layouts. Low EMI and noise make it ideal for sensitive electronics environments. Explore our catalog for more power management ICs and AC/DC Converters suitable for diverse industrial and commercial electronics applications.
