Integrated, Non-Isolated, Point of Load,

DC/DC Power Modules: 7~13.2Vin, 0.6-2.5V/ 3Aout

The MCM12S03L, 7V~13.2V input, single output, fully integrated non-

isolated point of load DC/DC converter is the latest offering from a world

leader in power systems technology and manufacturing －Delta

Electronics, Inc. This product family provides up to 3A of output current or

7.5W of output power in a compact, very low profile, miniature, IC-like,

very easy to use, molded package. It is highly integrated and requires

very few external components to provide the point-of-load function. The

back of the module is in close contact with the internal heat dissipation

components which provide excellent thermal performance. These

converters hence possess outstanding electrical and thermal

performance, as well as extremely high reliability under highly stressful

operating conditions. Operating over the input voltage ranges 7V to

13.2V, the MCM12S03L supports an output voltage range from 0.6V to

2.5V (with no power good) or 0.8V~2.5V (with power good), set by a

single resistor. The MCM12S03L is packaged in a thermally enhanced,

compact (18.6mm x 12.5mm), and low profile (4.2mm) over-molded

package suitable for automated assembly by standard surface mount

equipment. The MCM12S03L is lead free process compliant.
