6.2.3.7 PGOOD1 and PGOOD2 (pin 30 and pin 15)
Both of PGOOD1 and PGOOD2 are tied to BP5 with a 10-kΩ resistor.
6.2.3.8 CLKIO (pin 28)
CLKIO is open as no clock synchronization required for two phase configuration.
6.2.3.9 DIFFO, VOUT and GSNS (pin 1, pin 2 and pin 3)
VOUT and GSNS should be connected to the remote sensing output connector. DIFFO is connected to
the feedback resistor divider. If the differential amplifier is not used, VOUT and GSNS are suggested to be
grounded, and DIFFO is left open.
