LLC Controller Integrates Current Mode Control And Synchronous Rectification
Fairchild Semiconductor Corp.

Described as an industry first, the FAN7688 logs on as an advanced LLC resonant controller with current-mode control and synchronous rectification (SR). Promising best-in-class efficiency for isolated dc/dc converters, the device employs the company’s charge current control technology, which enables it to use current mode control, as opposed to voltage mode control. Current-mode control is a technique based on a charge control providing a better control-to-output transfer function of the power stage, simplifying the feedback loop design while allowing true input power limit capability. Closed-loop soft-start allows a monotonic rising of the output voltage regardless of load condition. The dual edge tracking adaptive dead time control minimizes the body diode conduction time, thus maximizing efficiency.
