AEC-Q100 Qualified Buck Regulator Power Module with Integrated Shielded Inductor designed for Medical and IT Infrastructure

RECOM has introduced two new automotive-grade buck converters that are fully protected against continuous short-circuits, output overcurrent, or over-temperature faults and are qualified for AEC-Q100 Grade 1 requirements. The new RPX-0.5Q and RPX-1.5Q feature an integrated inductor in a compact 3mm x 5mm x 1.6mm thermally-enhanced QFN package with wettable flanks and are suitable for automotive applications, industrial, medical, and IT infrastructure. Designated RPX-0.5Q and RPX-1.5Q, the DC/DCs respectively supply 0.5A and 1.5A from an input up to 36V with a trimmable output from 0.8V to 30V.

These devices include wettable flanks for Automated Optical Inspection (AOI) as required by the automotive industry. This gives low package thermal resistance and the economy of manufacturing, allowing cool-running and competitive end-product pricing. On/off control and synchronization inputs are provided along with a ‘power good’ output. The FCOL construction provides a low EMI signature with inherent screening, but if external filtering is required, a high, fixed-frequency operation makes this easier.
