Integrated, Non-Isolated, Point of Load,

DC/DC Power Modules:

4.5~5.5Vin and 7~13.2Vin, 0.8-2.5V/ 10Aout

The MCM12S10Q, 4.5~5.5V and 7V~13.2V input, single output, fully

integrated non-isolated point of load DC/DC converters are the latest

offering from a world leader in power systems technology and

manufacturing －Delta Electronics, Inc. This product family provides up

to 10A of output current or 33W of output power in an industry standard,

compact, IC-like, molded package. It is highly integrated and requires few

external components to provide the point-of-load function. Copper pads

on the back of the module in close contact with the internal heat

dissipation components 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 both the input voltage ranges 4.5V

to 5.5V and 7V to 13.2V, the MCM12S10Q supports an output voltage

range from 0.8V to 3.3V, set by a single resistor. The MCM12S10Q is

packaged in a thermally enhanced, compact (15mm x 15mm), and low

profile (3.5mm) over-molded package suitable for automated assembly by

standard surface mount equipment. The MCM12S10Q is lead free and

RoHS compliant.
