TPS65218D0: Pin settings when the system does not require an always-on power supply

Kaji@PAN

Part Number: TPS65218D0

Hello,

I would like to ask you if the system does not require an always-on power source, as shown in item 6.1.2 of the data sheet.
Can the following pins shown in Figure 6.2 be connected directly to the ground?
Or does each pin need to be pulled down at 10kΩ?
(Target pin)
IN_BU, CC, SYS_BU, L5, FB5, L6, FB6

Best regards,

Hi,

Thanks for using E2E! For applications using TPS65218D0 that don't require the always-on supplies (DCDC5 and DCDC6), the input and output of the power-path can simply be grounded. The 10KOhm resistor is not needed. Please note the PGOOD_BU and IN_nCC are kept floating.

Thanks,

Brenda
