RPX-4.0: High Power Density Cost-Effective 4A Buck Converters with Programmable 1-7V Output
RECOM has introduced the RPX-4.0, a 4A RPX series miniature buck converters with 3.8 to 36V input and programmable 1 to 7V output at 4A. In a compact 5mm x 5.5mm footprint and low 4.1mm height, the product features on-off control, a power good signal, and soft start, and is fully protected including under-voltage, short-circuit over-current, and over-temperature.
The device has been designed based on the 3D Power Packaging and offered in a thermally enhanced QFN package; it is optimized for high power density, with a flip-chip on leadframe construction, an integrated shielded inductor for low EMI, and intelligent control of switching frequency to maintain high efficiency even at light load. The RPX-4.0-EVM-1 evaluation board is also available for allowing customers to explore all the features of the RPX-4.0 buck converter.
