Secondary-Side Synchronous  
Forward Controller

DESCRIPTIO  
FEATURES  
The LTC®3726 is a secondary-side controller for synchro-  
nous forward converters. When used in conjunction with  
the LTC3705/LTC3725 gate driver and primary-side con-  
trollers, the part creates a complete isolated power supply  
that combines the simplicity of OPTI-LOOP® compensa-  
tion with the speed of secondary-side control.  
■
Secondary-Side Control for Fast Transient Response  
■
Self-Starting Architecture Eliminates Need for  
Separate Bias Regulator  
■
Proprietary Gate Drive Encoding Scheme Reduces  
System Complexity  
■
Current Mode Control Ensures Current Sharing

PLL Fixed Frequency: 100kHz to 500kHz  
±1% Output Voltage Accuracy  
OPTI-LOOP Compensation  
The LTC3726 has been designed to simplify the design of  
highlyefficient,secondary-sideforwardconverters.Work-  
inginconcertwiththeLTC3705orLTC3725,theLTC3726
