PF3000 unused outputs

Hello community,

 

I am using the PF3000 as the primary PMIC to power my MX7 based hardware.

 

For the first demo version of the board the 5V output was used for testing purposes, but it is not needed any longer.

May I cut some of the parts connected to the boost regulator? (Diode+Caps+Inductor ~ 50ct cost per device)

Or does the circuit need to be connected? In this case I could probably lower the capacitance values (currently 2x22uF+100nF+4.7uF).

Some LDOs are not used as well, simply using a small capacitor here should be the best option?

 

Regards,
Lars
