This circuit has both characters of restricting the current within the giving value and limiting the switching frequency of MOSFET operating on current limited condition.
该电路具有既能将负载电流限制在设定值以内,又能控制限流工作时功率管的开关频率等特点。

UC3846 of current mode control is used so that circuit for currentlimited function is removed and flux imbalance that can cause accident is been avoided.
