DESCRIPTION
The LTC®3706 is a PolyPhase capable secondary-side controller for synchronous forward converters. When used in conjunction with the LTC3705 gate driver and primary-side controller, the part creates a complete isolated power supply that combines the power of PolyPhase operation with the speed of secondary-side control.

FEATURES
■ Secondary-Side Control for Fast Transient Response
