V•I Chip VTM Level 1 DC Behavioral Model for 48 V to 9.6 V, 25.0 A

Figure 19—This model characterizes the DC operation of the V•I 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.

V•I Chip VTM Level 2 Transient Behavioral Model for 48 V to 9.6 V, 25.0 A

Figure 20—This model characterizes the AC operation of the V•I 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.
