RECOM Buck Converter
RECOM's buck converters contain the filter components to meet EMC Class A levels. There are alternate component positions included to experiment with the optimisation of EMC performance, all dependent on operating conditions and budget.
What does a buck converter do?A buck converter is used to lower the voltage of the given input voltage range (VDC) to achieve the required maximum current output (A). In short, a Buck converter connects the input to output to get a lower voltage. Buck converters are mostly used for point of load converters for computers, battery chargers, power audio amplifiers, and USB on the go.
For example, the RPL-3.0-EVM-1 Buck converter generates a constant output voltage selectable from 1.8V, 3.3V, or 5V from a DC input in the range of 4 – 18V. It has a maximum continuous output current of 3 A.
What are the advantages of a buck converter?There are numerous advantages of using buck converters, some benefits include:
- A higher efficiency from lower transitional losses
- A smaller output ripple voltage
- Transient performance is more efficient
- Require fewer external components in comparison to other evaluation boards (such as boost converters)
