Description
The highly integrated FAN6206 is a dual-channel
synchronous rectification (SR) controller. FAN6206
allows design of a cost-effective power supply with
fewer external components, especially suited for dual-
forward topology used to obtain higher efficiency for
ATX power supplies.
The primary-side control method provides synchronous
rectification control for dual-forward converters that
operate in continuous conduction mode (CCM).
FAN6206 includes a proprietary linear-predict timing
control mechanism for dual-forward converters that
operate in discontinuous conduction mode (DCM) at
fixed or variable frequency. PWM frequency tracking
with secondary-side winding detection is provided by
adding dividing resistors. The primary-side signals are
generated from Fairchild’s FAN6210 (Primary-Side
Synchronous Rectifier Signal Trigger for Dual-Forward
Converter). The primary-side signals are transferred
through a pulse transformer to the secondary-side. The
benefits of this technique include simple control method
and improved power system reliability.
FAN6206 is available in 8-pin SOP package.
