Aiming an IC implementation of a DC-DC converter which can provide a 4.5˜5 V stepped-up voltage for diode-lamps, a switched-capacitor (SC) DC-DC converter is proposed in this paper. Different from a conventional approach employing doubler circuits, the proposed circuit provides the output voltage by achieving a 3/2 step-up conversion. Therefore, decline in power efficiency for the proposed circuit is gentle. The process of DC-DC conversion is analyzed theoretically. To confirm the validity of the circuit design, SPICE simulations are performed. For the input voltage 3.2˜4.5 V, the power efficiency is 73˜92 % in the output current about 150 mA.
