Control circuit of high side and low side, and method for controlling the same

According to an embodiment of the present invention, a circuit for controlling upper and lower sides comprises: an upper unit composed of n (n is an even number higher than or equal to two) number of upper switches; an upper driver respectively connected to a half of the upper switches and a half of lower switches, and controlling turn-on and turn-off of the connected switches; and a lower driver respectively connected the remaining half of the upper switches and the remaining half of the lower switches, and controlling turn-on and turn-off of the connected switches. Therefore, the circuit realizes switching matching between upper and lower units.
