Abstract
Semiconductor module for a Switched-Mode Power Supply comprises at least one semiconductor power switch, a control semiconductor chip and a leadframe comprising a die pad and a plurality of leads disposed on one side of the die pad. The die pad comprises at least two mechanically isolated regions wherein the semiconductor power switch is mounted on a first region of the die pad and the control semiconductor chip is mounted on a second region of the die pad. Plastic housing material electrically isolates the first region and the second region of the die pad and electrically isolates the semiconductor power switch from the control semiconductor chip.
