Power modules provide high levels of integration

RECOM has partnered with a global OSAT company to expand its range of low-cost power modules. The RPX-1.0 and RPX-1.5 buck converters are offered in miniature, thermally-enhanced 3mm x 5mm QFN packages with 1.6mm profile and provide innovative 3D Power Packaging technology. Construction is over-moulded ‘Flip Chip on Leadframe’ with an integrated, shielded inductor, producing low EMI and high electrical and thermal performance. Each converter provides an input range of 4-36VDC and an adjustable output between 0.8VDC and 30VDC, set by external resistors. The RPX-1.0 is rated at 1A and the RPX-1.5 at 1.5A, each with typical full-load efficiency of 87% and the minimum of light-load losses. Depending on input/output voltage and load, peak efficiency can be over 95% and ambient operating temperature over 100C.

The modules are fully protected against short-circuit, over-current, over-temperature and input under-voltage and are equipped with enable, power good, soft start and external sync features. To enable rapid testing, the company also offers evaluation boards for the RPX so that customers can quickly and easily test.

RECOM Matthew Dauterive product manager DC-DC comments: “The wide input and output ranges of these highly integrated parts are ideal for 5, 12, or 24V nominal systems in industrial and motor control, ATE, medical, imaging and high-density power systems generally.”
