Description 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: 32µA operating unloaded and 0.1µA 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 1µF flying capacitors and two 10µF bypass capacitors are all that are required, and
no inductors are needed.
The LM2788 also features noise-reducing soft-start circuitry, short-circuit protection and over-temperature protection.
