Notes for DC Electrical Characteristics
Note 1
) VBREF=5.0V will assure full SCR firing on to produce the maximum amount of DC bus voltage and faster conver-
gence to the maximum DC bus voltage. Although VBREF=4.0V corresponds to the maximum voltage, it will take longer time
to converge to the maximum DC bus voltage.
Note 2)
These voltage values are linearly proportional to VLNSET. For example, if VLNSET = 2.0V, then all values are twice
of those values listed in the table.
Note 3)
VDD must be regulated within ±2.5%. VSS must be regulated within ±5%.
