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.
