SSOP Packages APPLICATIONS n n The LTC®3766 is a PolyPhase-capable secondary-side
controller for synchronous forward converters. When used
in conjunction with the LTC3765 active-clamp forward
controller and gate driver, the part creates a complete
isolated power supply that combines the power of multiphase operation with the speed of secondary-side control.
The LTC3766 has been designed to simplify the design of
active clamp forward converters. Working in concert with
the LTC3765, the LTC3766 forms a robust, self-starting
converter that eliminates the need for the separate bias …
