Product description:

FAN7688 Advanced Secondary Side LLC Resonant Converter Controller The FAN7688 is an advanced pulse frequency modulation (PFM) controller for LLC resonant converters with synchronous rectification (SR) that provides best-in-class efficiency for isolated DC/DC converters. It employs a charge control based current mode control technique in which a triangular waveform from an oscillator is combined with integrated switch current information to determine the switching frequency. This provides better control of the power stage to the output transfer function, which simplifies feedback loop design while allowing true input power limiting capability. Closed-loop soft-start prevents error amplifier saturation and allows the output voltage to rise monotonically regardless of load conditions. Dual edge tracking adaptive dead-time control minimizes body diode conduction time to maximize efficiency.

FAN7688 16-pin patch is used for ant miner APW12, APW8, APW9 power supply PWM main driver chip U9 position repair.
