Power Management

Power Modules - Silicon, IGBT and Silicon Carbide (SiC)

As subsystem designs get more complicated and board space becomes more valuable, many designers are considering using power modules instead of traditional discrete DC-DC Point-of-Load (POL) designs to reduce board size, improve reliability and speed up time to market.

Microchip’s highly integrated power modules contain a controller, power switches and the necessary passive components—all of which are fully tested and pre-characterized for EMI and DC performance—to offer a complete switching power supply solution. Offered in an ultra-compact, rugged and thermally enhanced package to improve high power density in your designs, these modules simplify your power design process while offering exceptional performance. Utilizing our proprietary Hyper Speed Control® architecture, they are designed to offer fast load transients to minimize output capacitance. Their HyperLight Load® mode provides efficiency improvements for light-load operation.

The Microchip Difference

Reducing Thermal Resistivity While Maintaining a Low Profile

Many industry solutions use die-in-PCB or die-over-PCB approaches. While these solutions make it easy to densely integrate the passive components, the plastics themselves are thermally resistive. Their poor thermal capabilities essentially negate their size advantage. The maximum operating temperature suffers and current capabilities get substantially de-rated over operating temperature. As a result, designers will require a larger, higher-current power module to meet the same application needs.

Microchip’s modules have superior thermal performance because they are built around thermally conductive copper lead frames instead of Printed Circuit Boards (PCBs). This allows operation up to the full-rated current, even at elevated temperatures, making the system more robust and more competitive in terms of both cost and size. The ultra-low profile combined with superior thermal performance enables the module to be placed under the PCB or on backplanes to save precious board space.
