MARKING DIAGRAM
Description The FAN7688 is an advanced Pulse Frequency Modulated (PFM) controller for LLC resonant converters with Synchronous Rectification (SR) that offers best in class efficiency for isolated DC/DC converters. It employs a current mode control technique based on a charge control, where the triangular waveform from the oscillator is bined with the integrated switch current information to determine the switching frequency. This provides a better control- to- output transfer function of the power stage simplifying the feedback...
