Question:admin
ut the output capacitor and the LED is still connected. If you do not load disconnect function, the output capacitor will discharge through the LED, turn on the power again until the PWM pulse. As the capacitor start of each PWM cycle are part of the discharge, the primary power source must be the beginning of each PWM cycle to the output capacitor charging. Therefore, each PWM cycle will be generated in the inrush current pulse. Inrush current will reduce system efficiency and transient generat
