The present invention relates to method of forming a switched mode power supply controller device with an off mode and a structure therefor. At least one embodiment is directed to a semiconductor voltage controller comprising: a start-mode circuit associated with a start-mode; and an off-mode circuit associated with an off-mode, wherein the voltage controller is operable to receive a feedback signal and an off-mode signal from a single input and provide an output voltage, wherein the voltage controller is operable to be in the off-mode when the feedback signal is less than a skip level and the feedback signal is less than a HV control level, and wherein the voltage controller is operable to be in start mode when the feedback signal is greater than HV control level and Vcc is below a Vcc-start.
