LTC3765  
Active Clamp Forward  
Controller and Gate Driver  
FEATURES  
DESCRIPTION  
The LTC®3765 is a start-up controller and gate driver for  
use in a self-starting secondary-side control forward con-  
verter. When combined with the LTC3766 secondary-side  
synchronousforwardcontroller,acompleteisolatedpower  
supply is created using a minimum of discrete parts. A  
proprietary scheme is used to multiplex gate drive signals  
and bias power across the isolation barrier through a  
small pulse transformer. The LTC3765 contains an on-  
chip bridge rectifier that extracts gate drive bias power  
from this pulse transformer, eliminating the need for a  
separate bias supply. A precision undervoltage lockout  
circuit and linear regulator controller ensure a quick and  
well-controlled start-up.

TheLTC3765includesanactiveclampoutputfordrivingan  
external PMOS, as well as an adjustable delay to optimize  
efficiency. The active clamp architecture reduces voltage  
stress on the main power switch, and provides the highest  
possible efficiency. Overcurrent protection and the Direct  
Flux Limit guarantee no transformer saturation without  
compromising transient response.
