The RECOM RPX DC/DC converters in QFN housings are also available as '-Q' variants which meet the strict requirements of the automotive industry according to AEC-Q100 Grade 1. Optionally, they can also be equipped with 'wettable flanks' for automated optical inspection (AOI).

The extremely small, lead-free, and thermally optimised 3 x 5 x 1.6mm housing operates with derating up to well over +100°C ambient temperature, both for the RPX0.5Q (0.5A) and the RPX-1.5Q variant (1.5A).

In the RPX series, the required inductance is already integrated. For full functionality, only external input and output capacitors adapted to the respective application are required.

On/off control and synchronisation inputs are equipped with a power-good output. The input voltage range of the converters is up to 36V. Output can be trimmed from 0.8V to 30V.

State-of-the-art integration and advanced 3D packaging technique

The over-moulded Flip-Chip-on-Leadframe (FCOL) construction used ensures the lowest thermal resistance of the enclosure. This makes it possible to keep manufacturing and end-product prices low.

Extensive protection mechanisms

The DC/DC converters are equipped with a soft-start function, as well as full short-circuit, overcurrent, over-temperature, and input under-voltage protection. Electromagnetic interference is kept low thanks to the FCOL design. A fixed frequency operation allows implementation of the required additional filtering.
