Abstract: A ballast for driving a gas discharge lamp includes an inverter configured to generate a lamp supply voltage signal, and a voltage regulator coupled to the inverter and configured to generate a regulation signal. The regulation signal is used by the inverter to maintain the lamp voltage signal at a substantially constant voltage. A thermistor circuit is coupled between the lamp supply voltage signal and the voltage regulator and configured to detect a temperature of the ballast. The lamp supply voltage signal is varied by the regulation signal in accordance with the detected temperature of the ballast.
