Figure 23 shows the UCD9220 power supply controller working with a single PTD08D210W power module. The
dual outputs of the PTD08D210W have been paralleled, allowing up to 20A of output current. When operating
the PTD08D210W in parallel configuration the dual inputs must be tied together and driven from a single output
of the digital power controller. Multiple PTD08D210W modules must not be paralleled.

Figure 23. Typical Paralleled-Output Application Schematic
Note 1: A low dropout linear regulator such as the TI TPS715A33 can provide the 3.3-V bias power to the UCD9220.
Note 2: An OR-gate such as the TI 74LVC1G32 should be used to sense a fault signal on either FF-A or FF-B.
