Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...

Optimized to operate from low input voltages such as those provided from a single- or dual-cell battery, the UCC39411/2/3 family of low-power synchronous boost converters are well-suited for use in ...

The advantages offered by a synchronous buck or boost topology can also be applied to a buck-boost topology, where the converter’s output voltage falls within its input range. In this case, a ...

A buck-boost DC/DC converter is one of the most valuable tools in a power supply designer’s toolbox for dealing with a variety of power conversion scenarios. In these situations, input voltages can ...
