The LM2788 switched capacitor step-down DC/DC converter efficiently produces a 120mA regulated low-voltage rail from a 2.6V to 5.5V input. Fixed output voltage options of 1.5V, 1.8V, and 2.0V are available. The LM2788 uses multiple fractional gain configurations to maximize conversion efficiency over the entire input voltage and output current ranges. Also contributing to high overall efficiency is the extremely low supply current of the LM2788: 32A operating unloaded and 0.1A in shutdown. The optimal external component requirements of the LM2788 solution minimize size and cost, making the part ideal for Li-Ion and other battery powered designs. Two 1F flying capacitors and two 10F bypass capacitors are all that are required, and no inductors are needed.
