Unused LX pin on LPC5536

[HPT_Dave]

If I'm not using the DCDC converter power stage output pin do I leave it unconnected? Table 4 of 6.2.1 Termination of unused pins does not specify.

Thanks for the help,

Dave

Hello @HPT_Dave 

If do not use DC-DC converter, make it as floating, using internal LDO hardware design as below:
