TOP247R-TL

The TOP247R-TL is an AC/DC converter integrated circuit designed for flexible power solutions. It belongs to the TOPSwitch-GX family and supports extended power ranges up to 290W in open frame designs and 165W in adapter configurations.

Key electrical features include programmable soft start, under-voltage detection, over-voltage shutdown, and externally programmable current limiting. It operates at a nominal frequency of 132 kHz with frequency jitter and selectable half-frequency operation. The device also incorporates line voltage feedforward and independent line voltage detection in the Y package.

For thermal management, it provides hysteresis thermal shutdown protection. The TOP247R-TL is available in various package types including TO-263-7C (R), TO-220-7C (Y), TO-262-7C (F), SMD-8C (G), and DIP-8C (P), supporting both through-hole and surface mount mounting types. The gap-pin design in standard packages enhances creepage distance.

Applications for this IC include LCD monitors, personal computers, small servers, laptop adapters, set-top boxes, digital TVs, printers, DVD players, UPS systems, video game consoles, broadband modems, mobile phone adapters, and audio amplifiers.
