Power Integrations AC/DC Converter 2.55 A, 50 V dc 7-Pin Through Hole DIP Package TNY290PG

Power Integrations TNY290PG AC/DC Converter is a compact, energy-efficient power management IC designed for offline applications requiring reliable power conversion. This device integrates a high voltage power MOSFET and an ON/OFF flyback controller within a 7-pin Through Hole DIP package, making it easy to implement in various electronic systems.

The TNY290PG supports a maximum input voltage of 265 V ac and delivers up to 2.55 A at 50 V dc output, with an output power rating of 14 W. Its flyback topology simplifies design and enables stable operation with excellent no-load and light-load efficiency.

Operating from temperatures as low as -40°C up to 150°C, it is suitable for industrial, commercial, and consumer electronics applications that demand high reliability under varying environmental conditions.

This AC/DC converter employs frequency jittering technology to reduce electromagnetic interference, thereby lowering EMI filter costs for the overall system. It also features accurate thermal shutdown protection with automatic recovery to enhance device and circuit safety.

Its self-biased design eliminates the need for a dedicated bias winding or extra bias components, simplifying the power supply design and reducing board space requirements.

Typical applications include power supplies for household appliances, industrial equipment, and other electronic devices where compact size and efficient power conversion are critical.

Maximum input voltage of 265 V ac ensures wide compatibility. Output power of 14 W supports moderate power requirements. Through Hole mount suitable for DIP package. Flyback topology provides simple and efficient design.

Wide temperature range of -40°C to 150°C enhances robustness. Compact dimensions 9.83 x 6.6 x 3.68 mm for space-constrained designs. Frequency jittering reduces EMI and related filter costs. Self-biased operation removes need for bias components.

Thermal shutdown improves reliability and safety. Low supply current of 930 μA for energy efficiency.
