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

Power Integrations TNY290PG AC/DC Converter is a TinySwitch-4 series energy-efficient offline converter combining a high-voltage power MOSFET and flyback power supply controller in a single compact 7-pin DIP package. Designed for industrial and electronic semiconductor power management circuits, it provides a maximum output current of 2.55 A and output voltage of 50 V dc with 14 W output power capability.

Its flyback topology enables simple ON/OFF control without the need for loop compensation, enhancing design simplicity and reducing costs. The converter supports input voltage range from 85 V ac minimum to 265 V ac maximum, suitable for diverse supply environments.

Designed to operate reliably from -40°C to 150°C, it includes accurate hysteretic thermal shutdown with automatic recovery and frequency jittering to reduce EMI filter requirements. Self-biased operation eliminates the need for bias winding or components, simplifying circuit design.

The device features a compact DIP package measuring 9.83 mm in length, 6.6 mm in width, and 3.68 mm in height with a through-hole mount, making it easy to integrate into printed circuit boards for power management applications in industrial, electronic components, and semiconductor sectors.
