Low-profile DC-DC power modules feature 99% efficiency

RECOM has introduced a new series of DC-DC converter modules which are compatible with the DOSA footprint, and which operate at very high efficiency of up to 99% to enable operation without a heat-sink. The corresponding evaluation boards offer a shortcut to the otherwise long-winded testing, as these boards provide customers with an effortless way to evaluate these modules.

The four new RPM modules, which are just 3.75 mm high, are notable for their high power density, the product of a new controller IC and a novel multi-layer PCB layout. The module’s surface-mount package is thermally optimized to draw heat away from the board: with no derating, it can supply more than 800W/in³ at a temperature of up to 90°C.

The RPM modules are rated for operation at full load over a wide temperature range of -40°C to 90°C. The power modules also help designers to achieve compliance with system EMC regulations, as they feature a ground plane in the PCB and a metal housing which provides six-sided shielding. The modules include input and output capacitors, and require no additional components.

Corresponding evaluation boards offer a shortcut to the otherwise long-winded testing, as the also available evaluation boards provide customers with an effortless way to test the RPM modules. The evaluation boards for the RPM‐1.0, RPM‐2.0, RPM‐3.0 and RPM‐6.0 buck regulator series generate a constant output voltage with an output current up to 6A from an external DC source.

Hereby the multitude of functions offered by the RPM power modules such as trimming, sequencing, soft‐start enable, and sensing can be evaluated. More importantly, the behavior in overload or over temperature can be easily assessed early in the design phase.

Converter samples, evaluation boards and OEM pricing are available from all authorized distributors or directly from RECOM.
