Typical Performance Characteristics Characteristic curves are similar for most

LTC6652s. Curves from the LTC6652-1.25, LTC6652-2.5 and the LTC6652-5 represent the extremes and typical of the voltage options.

Characteristic curves for other output voltages fall between these curves and can be estimated based on their output.
