... V goes below the stop voltage of 7.5V. CC Figure 17. Startup Block 2. Soft-Start: The FSGM0465R has an internal soft- start circuit that increases PWM comparator inverting input voltage, together with the SenseFET current, slowly after it starts. The typical soft-start time is 15ms. The pulse width to the power switching device is progressively increased to establish the correct working conditions for transformers, inductors, and capacitors ...

... SenseFET during the minimum turn-on time. Even though the FSGM0465R has overload protection not enough to protect the FSGM0465R in that abnormal case; since severe current stress is imposed on the SenseFET until OLP is triggered. The FSGM0465R internal AOCP circuit is shown in Figure 21. When ...

... To protect the device from this abnormal condition, OSP is included comprised of detecting V SenseFET turn-on time. When the V 2V and the SenseFET turn-on time is lower than 1.2μs, the FSGM0465R recognizes this condition as an abnormal error and shuts down PWM switching until V reaches V ...
