Hybrid converters can provide benefits in systems where efficiency, power density, and flexible power are important. In addition to pure voltage conversion, the LTM4654 can operate as both a current source and as a current sink. This means that bidirectional operation can take place to work with energy efficiently in a system.
The LTM4654 can also be used in the negative voltage range; for example, to convert +30 V to –7 V. This conversion takes place in a similar way to a buck regulator in the inverting buck-boost mode.
Furthermore, it is possible to operate several of these hybrid converters in parallel. With two converters, twice the current and thus twice the power can be converted.
