Introduction
One of the most common DC/DC converter problems is generating a regulated voltage that falls somewhere in the middle of a wide range of input voltages. When the input voltage can be above, below or equal to the output voltage, the converter must perform step-down and step-up functions. Unlike solutions requiring bulky transformers, the LTC3780 meets these requirements in the most compact and efficient manner, ...
