RECOM's new RPX-0.5Q and RPX-1.5Q are qualified to AEC-Q100 Grade 1 requirements, opening up more options for automotive applications, as well as providing an extra level of confidence for use of the products in other high-reliability areas, such as industrial, medical, and IT infrastructure.
Designated RPX-0.5Q and RPX-1.5Q, the DC/DCs respectively supply 0.5 A and 1.5 A from an input up to 36 V with a trimmable output from 0.8 V to 30 V.
RECOM’s 3D-Power Packaging
The products now include ‘wettable flanks’ for Automated Optical Inspection (AOI)
The parts are in a leadless, thermally-enhanced, over-molded QFN package, just 3 x 5 x 1.6 mm and feature RECOM’s ‘3D-Power Packaging’ techniques including Flip Chip on Leadframe (FCOL) internal construction. The products now include ‘wettable flanks’ for Automated Optical Inspection (AOI), as required by the automotive industry.
This gives low package thermal resistance and economy of manufacturing, allowing cool-running and competitive end-product pricing. Operation is to 125°C ambient with appropriate derating, and efficiency is high at over 90%, maintained down to light loads, helping to meet Eco Design targets.
FCOL construction
The products feature an integrated inductor and require just input and output capacitors, scaled for the application, to fully function. Comprehensive protection is included–input under-voltage, short-circuit, over-current, and over-temperature. 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, high, fixed-frequency operation makes this easier. Evaluation modules are available for both products.
