Abstract
A dual path and mode start-up circuit includes a high-voltage start-up circuit, an auxiliary start-up circuit, a capacitor, and a sensing circuit. The high-voltage start-up circuit has high-voltage input and output voltage nodes and is configurable to be operated in a first or second mode of operation. The auxiliary start-up circuit has auxiliary input and output voltage nodes. The auxiliary output voltage node, the high-voltage output voltage node, and the capacitor are in signal communication. The sensing circuit is configured to sense a voltage level at the capacitor and to configure the high-voltage start-up circuit to operate in the first mode of operation if the voltage level at the capacitor is less than a first threshold voltage level, and configure the high-voltage start-up circuit to operate in the second mode of operation if the voltage level at the capacitor is greater than a second threshold voltage level.
