Abstract
Disclosed herein is a switching converter capable of preventing a period in which a switch SW of a primary side is turned on and a period in which a synchronous rectifying switch SR SW of a secondary side is turned on from being overlapped with each other. The switching converter includes: a transformer T inducing primary energy to secondary side; a switch SW connected to a primary coil of the transformer T to switch a primary voltage; a synchronous rectifier SR connected to a secondary coil of the transformer T to rectify a secondary voltage; and a delay locked loop connected between the secondary coil and the synchronous rectifier SR, wherein the delay locked loop generates a signal synchronized with a turn-on control signal of the switch SW and outputs the generated signal to the synchronous rectifier SR to control a turn-off operation of the synchronous rectifier SR.
