The LTC3706 secondary-side synchronous controller and its companion smart gate driver, the LTC3725 are described. These two devices work together to make possible the creation of an isolated forward converter with the simplicity and performance of a buck converter.
isolated forward converter
Buck converter designers have long benefited from the simplicity, high efficiency and fast transient response made possible by the latest buck controller ICs, which feature synchronous rectification and PolyPhase interleaved power stages. Unfortunately, these same features have been difficult or impossible to implement in the buck ...
