LTC3706  
Secondary-Side Synchronous  
Forward Controller with  
PolyPhase Capability  
DESCRIPTION  
FEATURES  
The LTC®3706 is a PolyPhase capable secondary-side  
controllerforsynchronousforwardconverters.Whenused  
in conjunction with the LTC3705 gate driver and primary-  
side controller, the part creates a complete isolated power  
supply that combines the power of PolyPhase operation  
with the speed of secondary-side control.

Current Mode Control Ensures Current Sharing  
The LTC3706 has been designed to simplify the design  
of highly efficient, secondary-side forward converters.  
Working in concert with the LTC3705, the LTC3706 forms  
a robust, self-starting converter that eliminates the need  
for the separate bias regulator that is commonly used in  
secondary-side control applications. In addition, a pro-  
prietary scheme is used to multiplex gate drive signals  
and DC bias power across the isolation barrier through a  
single, tiny pulse transformer.
