Hourly load current
The load voltage is limited to about when the difference drops to the following. Note: When the input voltage is applied, the switch is enabled. When the pin becomes high for the first time, the turn back current limiting circuit works normally. The turn back current limiting circuit does not work at the second and subsequent time when the pin is high. According to the input and output capacitance values, the input inrush current may be higher than the expected value. This may cause the input voltage to drop. If the pin is connected to the pin From below at the beginning, when it is applied, the turnback current limiting circuit works normally. The enabled pin voltage of the device function mode must be higher than the threshold value to ensure that the device is fully enabled under all operating conditions. The minimum operating input voltage and the device do not include any special circuit at least before and the internal circuit cannot work completely before. The output voltage cannot be adjusted or whichever is higher

The customer should verify and test its design implementation to confirm the system function. Application information. Reverse voltage. When the voltage of the output pin is higher than the voltage of the input pin, there is a reverse voltage condition. Usually, when the voltage suddenly decreases and continues to be sufficient This happens when the charge causes the input to output voltage to become reverse. It is an uncommon case that when the AC voltage source is connected to the output terminal, there are two possibilities for the current to flow back from the output pin to the input when it is high enough to keep the control circuit active and the pin (only) If the input voltage is less than the programmed output voltage, the control circuit drives the gate of the element to the fully open state. In this case, the reverse current flows from the output pin to the input pin only by the element
