Power Integrations AC/DC Converter 1.05 A 50 V DC 7-Pin DIP TNY285PG

Power Integrations TNY285PG AC/DC Converter is a TinySwitch-4 series device optimized for offline, energy-efficient AC-DC power conversion. It integrates a high voltage power MOSFET and an ON/OFF flyback power supply controller in a compact 7-pin DIP package, enabling simplified design requiring minimal external components.

This converter supports a maximum input voltage of 265V AC and a minimum input of 85V AC, delivering a stable 6W output power at 50 V DC with a peak output current of 1.05 A. The flyback topology combined with a maximum duty cycle of 67% provides efficient voltage regulation with high transient response.

The device operates reliably over a wide temperature range from -40°C to 150°C, suitable for industrial, commercial, and consumer electronics applications. It features simple ON/OFF control eliminating the need for loop compensation, thereby reducing design complexity and costs.

Additional protections include accurate hysteretic thermal shutdown with auto-restart for overheating scenarios, and frequency jittering to minimize electromagnetic interference (EMI), reducing the need for extensive EMI filtering components.

Self-bias operation requires no bias winding or components, simplifying the power supply design further. This DIP package device measures 9.83 mm in length, 6.6 mm in width, and 3.68 mm in height, making it suitable for through-hole mounting.

Typical industrial and electronic use cases include power supplies for TVs, set-top boxes, adapters, and other compact electronic equipment requiring efficient AC to DC conversion with limited external components.
