Output equivalent circuit
The switching regulator controller output driving stage can be represented with an
equivalent circuit as in the Figure 13:
Figure 13.
Switching regulator controller output driving: equivalent circuit
As can be seen from the above figure, the external switch gate is charged with a current
generator ISOURCE and it is discharged towards ground with a current generator ISINK that is
applied for a TSINK pulse while an equivalent resistor RSUSTAIN is connected between gate
and source until the sink command is present.

Switching regulator controller application considerations
This controller can implement a step-down switching regulator used to provide a regulated
voltage in the range 0.8 V – 32 V. Such kind of variation could be managed by considering
some constraints in the application and particularly by choosing the correct feedback
reference voltage as indicated in the Table 13.
