An intraoral scanning device with a supply assembly unit

An intraoral scanning device configured to acquire intraoral scan data from a three-dimensional dental object, the intraoral scanning device includes:

• a projector unit configured to emit light at least onto the dental object of a patient based on a scan sequence, and wherein the projector unit includes one or more light sources, and the scan sequence includes a sequence of the emitted light of the one or more light sources;
• an image sensor configured to acquire reflected light from at least the dental object;
• a processing unit configured to process the acquired reflected light into 2D intraoral scan data and/or 3D intraoral scan data,
• a battery unit configured to supply a DC voltage, and
• a supply assembly unit configured to receive the DC voltage and provide a supply voltage to the one or more light sources, and the supply assembly unit includes:
• a voltage up-converter configured to convert the DC voltage to a supply voltage, wherein the DC voltage is lower than the supply voltage,
• a voltage down-converter configured to convert the DC voltage to a supply voltage such that the DC voltage is higher than the supply voltage, and
• a voltage controller unit configured to control the voltage up-converter and the voltage down-converter based on the scan sequence.
