Product Overview

The LTC3766EGN#PBF 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. It has been designed to simplify the design of active clamp forward converters. Working in concert with the controller forms a robust, self-starting converter that eliminates the need for the separate bias regulator that is commonly 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. It provides extensive remote sensing and output protection features, while Direct Flux Limit guarantees no transformer saturation without compromising transient response.
  • Direct Flux Limit™ guarantees no saturation
  • Fast and accurate average current limit
  • Clean start-up into pre-biased output
  • Secondary-side control for fast transient response
  • Simple, self-starting architecture
  • Synchronous MOSFET reverse current limit
  • PolyPhase® operation eases high-power design
  • True remote sense differential amplifier
  • Remote sense reverse protection
  • High voltage linear regulator controller
  • Internal LDO powers gate drive from VOUT
  • Overtemperature/overvoltage protection
