Switching regulators offer high efficiency

Mornsun introduces K78xx-2000 Series of three terminal switching regulators.

Hudson, Mass., November 17, 2010—Mornsun introduces the new K78xx-2000 Series of three terminal switching regulators that are an efficient, drop-in replacement for linear regulators. Highly efficient operation (up to 92 percent) results in low heat dissipation, eliminating the need for a heatsink, saving board space and cost.

The K78xx-2000 products are the latest in Mornsun’s family of switching regulators. The Series offers input ranges spanning 4.75 Vdc to 18 Vdc, with positive or negative outputs of 2.5 Vdc, 3.3 Vdc, 5 Vdc and 6.5 Vdc. An output current rating of up to 2A allows for up to 13W of power in a miniature SIP package with a choice of straight or bent leads.

The operating temperature of the K78 Series is -40C to +85C. Units feature short circuit protection, low output noise, thermal shutdown and a high MBTF of 2000K hours. The K78 Series uses high quality, 100 percent RoHS compliant materials and are manufactured to Mornsun’s rigorous, ISO-9001 quality control program to ensure high product reliability.
