Power Integrations AC/DC Converter 12V 6-Pin TO-220 70W TOP248YN

Power Integrations TOP248YN is a high-performance AC/DC Converter designed for reliable and efficient power management in electronic systems. This device integrates a high voltage power MOSFET, PWM control, fault protection, and various control circuitry on a single CMOS chip, providing an all-in-one solution for power conversion.

Featuring a 12V output voltage and maximum output power of 70W, the TOP248YN operates with a maximum input voltage of 265V AC and a minimum input voltage of 85V AC, ensuring flexibility and compatibility with common AC power sources. The device is housed in a compact TO-220 package with 6 pins, supporting through-hole mounting for secure installation.

Its flyback topology and switching frequency of 132kHz enable efficient energy conversion while maintaining low electromagnetic interference. With a maximum duty cycle of 66.5%, the device supports higher power applications without compromising stability. Operating temperatures between -40°C and 150°C ensure durability in demanding industrial environments.

The integrated soft-start reduces inrush current and stress on components during power-up. Additional protections such as line under-voltage detection, line overvoltage shutdown, and externally programmable accurate current limit enhance operational safety. The device achieves zero load regulation without the need for dummy loading and is designed to be eco-friendly with energy-efficient features.

Its low supply current of 1mA further contributes to overall system efficiency, and the device does not require a heatsink for power levels up to 34W, reducing design complexity. The TOPSwitch-GX series from Power Integrations is a trusted solution widely used in industrial, consumer electronics, and power supply applications where robust and efficient AC/DC conversion is required.

Maximum input voltage of 265V AC for reliable operation. 12V regulated output for versatile applications. Compact TO-220 6-pin package for easy mounting. 132kHz switching frequency for efficient power conversion. Wide operating temperature range from -40°C to 150°C.
