Isolated Converters Have Buck Simplicity and Performance
Design Note 377
Kurk Mathews
Buck converter designers have long beneп¬Ѓted from the
simplicity, high efп¬Ѓciency and fast transient response
made possible by the latest buck controller ICs, which
feature synchronous rectiп¬Ѓcation and PolyPhaseВ® interleaved power stages. Unfortunately, these same features
have been difп¬Ѓcult or impossible to implement in the
buck converterвЂ™s close relative, the forward converter,
often used in isolated industrial and telecom applications. That is, until now. The LTC В®3706 secondary-side
synchronous controller and its companion smart gate
driver, the LTC3725, make it possible to create an isolated
forward converter with the simplicity and performance
of a buck converter.
Simple Isolated 3.3V, 30A Forward Converter
Many isolated supplies place the controller IC on the
input (primary) side and rely on indirect synchronous VIN+

LвЂ‰DESIGN FEATURES Isolated Forward Controllers Offer
Buck Simplicity and Performance
by Charles Hawkes and Arthur Kelley 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 PolyPhaseВ®
operation. Unfortunately, these
same features have been difficult or
impossible to implement in the buck
converterвЂ™s close relative, the forward
converter. That is, until now. The
LTC3706/26 secondary-side synchronous controller and its companion
smart gate driver, the LTC3705/25,
make it possible to create an isolated
forward converter with the simplicity
and performance of the familiar buck
converter. rectifier timing and optoisolator feedback to control the output (secondary).
This architecture is commonly known
as primary-side control. By contrast,
secondary-side control places the
controller IC on the secondary side,
and uses a gate-drive transformer …
