In the Application Schematic 2, the AT73C224-B is used: the BOOST (VO1) supplies the
“VBUS” of one USB transceiver and supplies also LDO3 and LDO4. The BUCK(VO2) supplies
the digital core of the microcontroller and the LDOs supply the I/Os and Analog cells, such as
auxiliary ADC or PLL.
For external components, see Table 4-1 .
