DESCRIPTION
The LTC®3726 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.

FEATURES
■ Secondary-Side Control for Fast Transient Response
