Japanese Patent JP5822209
Kind Code:
B2
Abstract:
In one embodiment, an apparatus includes a transistor having a gate, a drain, and a source. The drain is coupled to receive an AC power supply signal. A component is coupled between an output node and the gate of the transistor. The component couples an output voltage from the output node to charge a gate-source capacitor during a first portion of the AC power supply signal. The transistor is configured to turn on during a second portion of the AC power supply signal to send a charge to the output node where the charge is used to power a circuit of a power supply.
