V110A12E300BF3

Application Field

The V110A12E300BF3 can be used to provide power to several electrical appliances, such as laptop computers, tablets, and cellular telephones. This DC-DC converter can also be used for EV and HEV applications, where it can provide service as the primary converter or as an auxiliary converter. This converter is also popular within renewable energy sources such as wind turbines and solar plants.

Working Principle

The V110A12E300BF3 is a buck-boost converter that is designed in such a way as to allow it to accept wide input voltages of between 8.0V and 56V DC when operating in auto mode, or between 5.9V and 21V DC when operating in manual mode. The converter boasts 300 watt output power, and can handle up to 1,800A of output current, in addition to offering multiple converter disconnect features.

This DC-DC converter uses the Flyback topology for power transfer, meaning it stores the energy from the input side to the transformer during a windup phase, and then uses this energy to power the output load. While Flyback converters are able to store more energy than other topologies, which in turn means a larger transformer, this DC-DC converter has a relatively small form factor thanks to its high frequency switching.

This converter is highly efficient, with average efficiency levels of above 95%, meaning users benefit from decreased power losses when using this converter. Since the converter features both manual and auto modes, it is also straightforward to use.
