Table 13: Suggested components for the VCC voltage supply application circuit using a step-down regulator
Figure 28Figure 28 and the components listed in Table 14Table 14 show an example of a low cost power
supply circuit, where the VCC module supply is provided by a step-down switching regulator capable of
delivering 1.9 A current pulses, transforming a 12 V supply input.
