Recom – RPX-1.0 and RPX-1.5 – buck regulator power modules with wide input and output voltage ranges

RECOM has extend their range of low-cost power modules. The RPX-1.0 and RPX-1.5 buck converters are available in miniature, thermally-enhanced 3mm x 5mm QFN package with 1.6mm profile and feature innovative 3D Power Packaging technology. Construction is over-molded ‘Flip Chip on Leadframe’ (FCoL) with an integrated, shielded inductor, resulting in low EMI and high electrical and thermal performance. Each converter has an input range from 4 to 36VDC and an adjustable output voltage between 0.8 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 minimal light-load losses. Depending on input/output voltage and load, peak efficiency can be over 95% and ambient operating temperature over 100°C.

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. For easy evaluation Eval Boards are available for both types, so customers are able to test quickly and easily.
