The LTC3726 is a secondary-side controller for synchronous forward converters. When used in conjunction with the LTC3705/LTC3725 gate driver and primary-side controllers, the part creates a complete isolated power supply that combines the simplicity of OPTI-LOOP compensation with the speed of secondary-side control. The LTC3726 has been designed to simplify the design of highly efficient, secondary-side forward converters. Working in concert with the LTC3705 or LTC 3725, the LTC3726 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 proprietary scheme is used to multiplex gate drive signals and DC bias power across the isolation barrier through a single, tiny pulse transformer. The LTC3726 is available in a 16-lead SSOP package. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation. OPTI-LOOP is a registered trademark of Linear Technology Corporation.
