6 Devices With Internal Reference Voltage

Some devices are built with a low pin count design constraint. In this case, a reference voltage input falls outside the design scope. The reference voltage is internally configured with the only means to change the actual current regulation point by selecting a particular SENSE resistor. Users must refer to the respective device’s datasheet to determine the internal reference voltage parameter.
