The 1A output is available at ambient temperatures above 80°C, depending on the input/output voltage combinations, with operation up to 125°C possible with power reduction. Efficiency is up to 95%.
The RPH-3.0 is housed in a 47-pin QFN package, measuring 10 x 12 mm and 4 mm in height. It provides a 3A output with an input range of 4.5 to 55V and an adjustable output range of 1 to 15V. Efficiency reaches up to 91%, and full output current can be maintained above 80°C with, for example, a 12V input and 3.3V output.
The RPL-10 component has a nominal output of 10A and boasts a wide range of features. Housed in an LGA-M package measuring only 7 x 7 mm and 4.4 mm in height, the regulator has an input range of 4 to 16V and a programmable output of 0.6 to 5.5V. Its high efficiency, up to 94%, allows operation at temperatures up to 90°C under full load. The operating frequency is selectable between 600kHz and 800kHz, control is achieved via constant on-time for fast transient response, and a pulse skip mode maintains efficiency under light loads.
Finally, the RPL-20 takes power density to a new level with its 20A capacity and programmable output from 0.6 to 5.5V. The input range is 4 to 16V, and the efficiency is up to 94%, allowing operation at ambient temperatures up to 90°C under full load. The package size is the same as the RPL-10, at 7 x 7mm and 4.4mm high, effectively doubling the power density. The operating frequency can be adjusted between 600kHz and 1MHz, with forced continuous drive and pulse omission modes as selectable options.
All the products described have integrated magnets and include a remote on/off function, a good operation signal, and comprehensive protection against input undervoltage, overheating, short circuits, and output overload.
“These step-down converters are ideal for use in confined spaces where high efficiency is also required,” says Matthew Dauterive, MSc, DC/DC product manager at RECOM. “They excel in applications such as portable devices, imaging systems, distributed power architectures, and FPGA power supplies, as well as general telecommunications and industrial uses.”.
The parts include a three-year warranty. Samples and OEM pricing are available through authorized distributors or directly from RECOM.
