Bus Powered Application example 2: Bus powered configuration (with additional 1.8V LDO voltage
regulator for VCORE)
Figure 6.2 Bus Powered Configuration Example 2
Figure 6.3 illustrates the FT2232H in a typical USB bus powered configuration similar to Figure 6.1. The
difference here is that the +1.8V for the FT2232H core (VCORE) has been regulated from the VBUS as
well as the +3.3V supply to the VPLL, VPHY, VCCIO and VREGIN.
