A voltage multiplier and driver circuit for energizing a backlight or lamp device in a timepiece. The circuit includes switching transistors responsive to an alternating signal for alternately disconnecting the lamp (load) while a capacitor is connected across a DC voltage source and for reconnecting the lamp (load) across a series (voltage additive) connection of the DC voltage source and the charged capacitor. The alternating signal frequency and duty cycle are selected to energize the lamp (load) to a predetermined color temperature.
