VI Chip VTM LEVEL 1 DC BEHAVIORAL MODEL for 48V to 1.5V, 90A
Figure 20
—This model characterizes the DC operation of the VI Chip VTM, including the converter transfer function
and its losses. The model enables estimates or simulations of output voltage as a function of input voltage and output load, as
well as total converter power dissipation or heat generation.

VI Chip VTM LEVEL 2 TRANSIENT BEHAVIORAL MODEL for 48V to 1.5V, 90A
Figure 21
—This model characterizes the AC operation of the VI Chip VTM including response to output load or input voltage
transients or steady state modulations. The model enables estimates or simulations of input and output voltages under transient
conditions, including response to a stepped load with or without external filtering elements.
