Abstract: The present invention relates to a secondary resonant buck converter capable of soft switching. In particular, the buck converter performs a zero-current switching operation by a secondary resonance when a switch is on, and performs a zero-voltage switching operation when the switch is off so as to minimize loss of switching. A constant current circuit for operating an LED is easily implemented by using the buck converter.
