L6699 LLC Resonant Half-bridge Controller IC Slide 12

This slide lists the details of the L6699 control chip, including several functions and features that are noteworthy. One of the most important features is an auto-adjusting adaptive dead-time. In addition to that the improved burst mode function realizes low standby power consumption. The anti-capacitive mode protection, the latched disable input function, and a separate input for brownout protection increase the robustness of the power supply designed around this IC. In addition, it also features a nonlinear soft-start function, which ensures monotonic output voltage rise at start-up and an enhanced control method that prevents any dangerous hard-switching from occurring during start-up. One feature that is not mentioned on the slide is that the L6699 is pin-for-pin compatible with the original L6599A, therefore switching from one to the other is a very simple process.
