.Data Sheet.co.kr Features n n LTC3766 High Efficiency, Secondary-Side Synchronous Forward Controller DESCRIPTION The LTC®3766 is a Poly Phase-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 plete isolated power supply that bines 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 regulator that is monly used in secondary-side control applications. A precision current-limit coupled with clean start-up into a pre-biased load make the LTC3766 an excellent choice for high-power battery charger applications. The LTC3766 provides extensive remote sensing and output protection Features , while Direct Flux Limit guarantees no transformer saturation without promising transient response. A linear regulator controller and internal bypass LDO are also provided to simplify the generation of the secondary-side bias voltage.
