A packaged circuit and method for packaging an integrated circuit are disclosed. The packaged circuit has a lead frame, an integrated circuit chip, and an encapsulating layer. The lead frame has first and second sections, the first section including a lateral portion, a chip mounting area and a first extension. The integrated circuit chip is mounted in the chip mounting area and is in thermal contact with the chip mounting area. The encapsulating layer has top, bottom, and first and second side surfaces. The first extension is bent to provide a first heat path from the chip mounting area to the bottom surface. The heat path connects the heat chip mounting area to the bottom surface without passing through the first and second side surfaces and provides a heat path that has less thermal resistance than the heat path through either the lateral portion or the second section. |
