PRODUCTION DATA.
The DMD HV regulator generates three high voltage supplies: DMD_VRESET, DMD_VBIAS, and DMD_VOFFSET (see Figure 14). The DMD HV regulator uses a switching regulator (switch A through switch D), when the inductor shares time between all three supplies. The inductor charges to the current limit threshold and then discharged into one of the three supplies. The regulator distributes available charge time between those supplies that require a charge and when not all supplies require a charge.
