Power Integrations AC/DC Converter 3 Amp 11W 265V ac 8-Pin DIP-C Through Hole TNY265PN

Power Integrations TNY265PN is a highly integrated AC/DC converter IC designed to deliver reliable power management in electronic circuits, particularly suited for compact and cost-effective power supply designs. The device integrates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit circuitry, and thermal shutdown logic into a single monolithic chip, enabling simplified power conversion implementations.

This 8-pin DIP-C package module supports a maximum output current of 3 A and output power rating of 11 W, with an input voltage operating range from 85 V AC to a maximum of 265 V AC. The flyback topology employed allows for efficient energy transfer while maintaining compact device size, aided by its 132 kHz switching frequency which minimizes electromagnetic interference and enables the use of smaller transformers.

The TNY265PN features automatic restart functionality providing robust short circuit and open loop fault protection, eliminating the need for many external components and reducing external cost and complexity. The built-in programmable line under-voltage detection prevents power interruptions and glitches during power cycling events. Frequency jittering effectively reduces EMI by approximately 10 dB, thereby minimizing the necessity for heavy EMI filtering.

Designed for through hole mounting, the device measures 9.83 mm length, 6.6 mm width, and 3.68 mm height, supporting easy integration onto PCBs. Its operating temperature range spans from -40°C to 150°C, making it suitable for diverse industrial and electronic applications. The supply current is low at 245 μA, contributing to energy efficiency.

Certified to meet ENERGY STAR guidelines, EU requirements, and California Energy Commission standards, the TNY265PN meets stringent energy and safety regulations. Typical applications include power adapters, standby power supplies, and other consumer or industrial electronic devices requiring efficient AC/DC conversion.
