摘要: An off-line regulator has a rectification circuit configured to rectify an AC line voltage into a rectified line voltage, a pass device coupled between the rectified line voltage and a first capacitor, and a converter. The pass device is configured to be turned ON or OFF according to a comparison signal indicating whether the rectified line voltage is over a threshold voltage. The first capacitor delivers an interim voltage into the converter which supplies power to a load. Wherein a second capacitor coupled across a driver which driving the pass device is charged by the first capacitor when the comparison signal is at a first state, and the driver is boosted when the comparison signal is at a second state.
