Functional Description
MC13783 Technical Data, Rev. 3.5
Freescale Semiconductor 23
4.2 Switchers and Regulators
4.2.1 Supply Flow
The switch mode power supplies and the linear regulators are dimensioned to support a supply flow based
upon Figure 5.
Figure 5. Supply Distribution
The minimum operating voltage for the supply tree, while maintaining the performance as specified, is 3.0
V. For lower voltages the performance may be degraded.
Table 9 summarizes supply output voltages.
