PRELIMINARY  
Application Note (continued)  
V•I Chip Bus Converter Module  
The thermal resistance of the PCB to the surrounding environment in  
proximity to V•I Chips may be reduced by low profile heat sinks surface  
mounted to the PCB.The PCB may also be coupled to a cold plate by low  
thermal resistance standoff elements as a means of achieving effective  
cooling for an array of V•I Chips, without a direct interface to their case.  
CASE 3—Combined direct convection to the air and conduction to the PCB.  
Parallel use of the V•I Chip internal thermal resistances (including Junction-  
to-Case and Junction-to-BGA) in series with external thermal resistances  
provides an efficient thermal management strategy as it reduces total  
thermal resistance. This may be readily estimated as the parallel network of  
two pairs of series configured resistors.

Figure 25—This model characterizes the DC operation of the V•I Chip bus converter, 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.

Figure 26—This model characterizes the AC operation of the V•I Chip bus converter 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.
