A switch-mode voltage converter has a switching transistor coupled between an input voltage (Vin) and the ground and a controller coupled directly between the input voltage (Vin) and the ground. The controller periodically turns on the switching transistor for a generally constant period of time. The controller is further coupled to a DC bias voltage (Vbias) and generates a control current based on the input voltage (Vin) and the DC bias voltage (Vbias) for generating a switching signal to the switching transistor.
