It fulfils the requirement of minimum external control circuitry for a flyback application. Current mode control means that the current through the CoolMOS transistor is compared with a reference signal derived from the output voltage of the flyback application. The result of that comparision determines the on-time of the CoolMOS transistor. The accuracy of the switching frequency is highly sophisticated due to temperature compensation. Furthermore overload and open loop protection is implemented by sensing the feedback line.
