DC/DC converter range meets AEC-Q100

The successful RECOM RPX QFN-packaged DC/DC converters now have ‘-Q’ variants which meet stringent automotive AEC-Q100 Grade 1 requirements and have been upgraded to include ‘wettable flanks’ for Automated Optical Inspection (AOI). The DC/DCs have an input range up to 36V, and the output can be trimmed from 0.8V to 30V. The RPX-0.5Q variant delivers 0.5A, and the RPX-1.5Q delivers 1.5A, both in a tiny 3 x 5 x 1.6mm leadless, thermally-enhanced QFN package, operating to well over 100°C ambient with derating. This is enabled by state-of-the-art integration and advanced 3D packaging techniques using an over-molded Flip Chip on Leadframe (FCOL) construction to provide lowest package thermal resistance while keeping manufacturing and end-product pricing low.

The RPX series integrates the necessary inductor and requires just external input and output capacitors, scaled for the customer’s application, for full functionality. On/off control and synchronisation inputs are provided with a power good output. Soft start along with full short circuit, over-current, over-temperature, and input under-voltage protection is included. Due to the FCOL construction, EMI is low, and fixed-frequency operation makes any required additional filtering easy to implement.

Evaluation modules are available for both products.

Matthew Dauterive, DC/DC Product Manager of RECOM comments; “The success of our RPX range has spurred us on to further qualify them to automotive standards. This gives our customers extra confidence that they can also be used in other application areas such as industrial or ATE, with high reliability”.

The RPX0.5Q and RPX-1.5Q series are available through all authorized RECOM distributors or by contacting the manufacturer directly. Samples can be requested via the RECOM website.
